CJ Henley, DMD, PA / San Marco, Jacksonville / Serving Mandarin
A dentist for Mandarin, Jacksonville.
Implants, dentures, cosmetic and same-day emergency care.
Our office is not in Mandarin. It is in San Marco, at 3675 Hendricks Avenue, about 7 to 12 miles north of most of Mandarin on one road, San Jose Boulevard. Mandarin patients make that drive for dental implants placed and restored in one office, help with loose or broken dentures, crowns and veneers that need redoing, and care that has to fit a complicated medical history. If you have a dental emergency, call first: we see emergencies the same day during office hours, and new patients are welcome.
Existing patients after hours: call or text our on-call line, 904.762.5616. Se habla español.

Mandarin to San Marco
Why Mandarin patients drive to San Marco, and when a closer dentist makes more sense.
Most Mandarin patients come to us for care that takes planning: dental implants, a fix for a loose or broken denture, crowns or veneers that need redoing, badly worn teeth, or dental care around cancer treatment or a serious medical condition. For a routine cleaning and checkup, a dentist in Mandarin may simply be more convenient, and we will tell you that.
Mandarin has plenty of good dental offices. What it has fewer of is a general dentist whose day is mostly restorative and complex work: dental implants that the same dentist places and then restores, full-arch implant teeth, second opinions on crowns and bridges that failed, and care for people whose health makes dentistry harder. That is the work that brings people from Mandarin up San Jose Boulevard to our side of Jacksonville.
The trip is shorter than it sounds. From Loretto Road to our door is about 9.6 miles, and from north Mandarin near Crown Point Road it is about 7 (routes below). Patients also come to us from across Florida and from other states, so a Mandarin visit is a short one by comparison.
If all you need is a cleaning twice a year and your teeth are healthy, a dentist five minutes from home is a reasonable choice. Many of our Mandarin patients do the big work here and keep a closer office for routine care, and others make our general and family dentistry their dental home for the whole family.

Emergency dentist for Mandarin
Same-day emergency dental care for Mandarin, if you call first.
If you live in Mandarin and have a toothache, a broken tooth, a lost crown, swelling, or a knocked-out tooth, call 904.398.1549 as early in the day as you can. We see dental emergencies the same day during office hours, including new patients, and we tell you what to do on the drive up San Jose Boulevard.
What we treat the same day
A bad toothache, a broken or cracked tooth, a lost crown, filling, or veneer, an abscess or facial swelling, a knocked-out tooth, children’s dental injuries, and a broken denture or loose implant crown. Emergency visits are call-first, not walk-in, so we can hold a chair and have your records ready.
Is the drive from Mandarin worth it in an emergency?
For most dental emergencies, yes: 15 to 25 minutes is rarely what decides whether a tooth can be saved. The exception is a knocked-out adult tooth, where minutes matter; read the knocked-out tooth steps before you leave, keep the tooth in milk, and call us from the car. Our same-day emergency visit page explains what happens when you arrive.
you have trouble breathing or swallowing, swelling near your eye or down your neck, a fever with facial swelling, bleeding that won’t stop with firm pressure, or a possible broken jaw. In Mandarin, HCA Florida Mandarin Emergency at 10910 San Jose Boulevard is open 24 hours. Once you are stable, call us and we will treat the tooth. See ER or dentist?

Dental implants for Mandarin patients
Dental implants placed and restored in one office.
Dr. Henley both places dental implants and makes the teeth that go on them, so one dentist plans the whole case from the first 3D scan to the final crown, bridge, or full-arch teeth. We place single-tooth implants, fixed full-arch implant teeth (All-on-X), and the extractions and bone grafting that often come first.
One missing tooth
A single implant replaces one tooth without cutting down the teeth beside it, which a bridge requires. Our post on dental bridge vs implant walks through the tradeoffs, and the implant options section compares them side by side.
Full-arch implant teeth (All-on-X)
For someone missing most or all of the teeth in a jaw, or tired of a loose denture, several implants can hold a fixed arch of teeth that you don’t take out at night. The case below used six implants in each jaw.
Extractions and bone grafting
After a tooth is removed, the bone shrinks: in a review of human studies, ridge width fell by about 29 to 63 percent in six to seven months.2 When an implant is planned, we often graft the socket at the extraction visit so there is bone to place it in later.
Planned in 3D
Implants are planned with cone beam 3D imaging, so we can see bone height, width, and nearby nerves and sinuses before surgery. See the step-by-step implant process.
Implants are one option, not the answer for everyone. Radiation to the jaws, some bone medications, uncontrolled diabetes, and heavy smoking all change the risk, and for some people a bridge or a well-made denture is the better choice. We explain why at your exam; read about osteoporosis medications and dental health.
Real patients from our San Marco office
Dental implants before and after.
These are two of our own implant patients: one with no upper teeth who now has fixed full-arch teeth on both jaws, and one whose failing crowns and bridges were replaced with implants and new porcelain-fused-to-zirconia restorations. Drag the slider on each photo to compare.
All-on-X full-arch implants on both jaws
This patient had no upper teeth. We placed six implants in each jaw, planned with 3D imaging and a surgical guide, and attached fixed full-zirconia hybrid bridges. Unlike dentures, they are screwed to the implants: no adhesive and no plate over the roof of the mouth. Read the full case.
Failed crowns and bridges replaced with implants
Several old crowns and bridges were breaking down. Teeth that couldn’t be saved were replaced with dental implants, the gumline was reshaped with a laser, and the upper arch was rebuilt with porcelain-fused-to-zirconia bridges and crowns. Read the full case.
See more implant, crown, and veneer cases in our before and after gallery and the longer write-ups in case studies.
Dentures for Mandarin patients
Loose, broken, or done with dentures: what we can do.
If your denture breaks, call us: denture repairs are one of the emergencies we see the same day during office hours. We make new complete and partial dentures and reline dentures in our office. If the real problem is a denture that won’t stay in, the answer may be a reline, a new denture, a snap-in implant overdenture, or fixed implant teeth that you never take out. We look at your gums, bone, and bite and explain which fits you.
| Feature | Removable denture | Snap-in implant overdenture | Fixed full-arch implant teeth (All-on-X) |
|---|---|---|---|
| How it stays in | Suction, gums, and sometimes adhesive | Snaps onto two or more implants; you remove it to clean | Screwed to several implants; only the dentist removes it |
| Roof of the mouth | An upper denture usually covers the palate | A lower overdenture is the most common; an upper may still cover part of the palate | Open palate |
| Bone over time | The ridge keeps shrinking, so dentures loosen and may need relining or remaking3 | Implants help preserve the bone they sit in | Implants load the bone they sit in |
| Surgery | None, beyond any extractions | Implant surgery for fewer implants than a fixed arch | Implant surgery, often with extractions and grafting |
| Daily care | Out at night, brushed and stored in water3 | Removed daily to clean the denture and the implant attachments | Brushed in place; professional cleanings with the teeth removed |
A broken or cracked denture
Bring all the pieces and don’t glue them; drugstore glue makes a proper repair harder. Many denture repairs can be done the same day. See broken dentures and loose implant crowns.
A denture that keeps getting looser
As the jawbone under a denture shrinks, the fit changes, and sore spots, clicking, and slipping follow. Sometimes the fix is a reline we do in our office; sometimes it is time for a new denture, a snap-in overdenture, or fixed implant teeth. A comprehensive exam with 3D imaging shows how much bone is left for implants.
We place and restore both snap-in implant overdentures and fixed full-arch implant teeth like the case above. A snap-in overdenture is a big step up in stability from a loose lower denture; fixed teeth never come out. At the consultation we show you both and help you choose.
Cosmetic and restorative care for Mandarin
Crowns, veneers, worn teeth, and redos of work done elsewhere.
A lot of the cosmetic dentistry we do for Mandarin patients is fixing what didn’t turn out right: veneers that look bulky or fake, crowns that don’t match, and teeth worn short by grinding. We plan from a preview you approve, and our porcelain is hand-layered by a named ceramist.
Veneers and veneer redos
Our porcelain veneers are layered e.max made by ceramist Paul Robert at Dynamic Dental Solutions, usually over about three visits. You see a mock-up before any tooth is prepared. If yours look wrong, read why veneers look fake and how they are redone.
Crowns and bridges that failed
Dark lines at the gum, a crown that looks like a cap, or a bridge that keeps coming loose are reasons for a second opinion, not proof everything must be replaced. Read why you might need a crown and why crown fees vary in Jacksonville.
Teeth worn down by grinding
Teeth that look shorter every year are often a sign of teeth grinding (bruxism). We rebuild worn teeth with strong porcelain and protect them with a custom night guard; see a case of teeth worn down by grinding.
Whitening, bonding, and aligners first
The least invasive option comes first. Sometimes teeth whitening, a little bonding, or clear aligners gets the result without veneers. More on our approach to cosmetic dentistry.
When your health is part of the plan
Complex and medically involved dental care.
If you are facing head and neck cancer treatment, recovering from radiation, taking medications that affect your jaw or mouth, or living with a condition that makes dental care harder, your dental plan has to fit your medical one. That coordination is a large part of Dr. Henley’s work, and it is a common reason Mandarin patients choose our office.
Head and neck cancer dental care
Dr. Henley is a member of the Head and Neck Tumor Board at Baptist MD Anderson. The National Institute of Dental and Craniofacial Research advises seeing a dentist about a month before cancer treatment begins.4 We see patients before, during, and after head and neck cancer treatment, including dry mouth, jaw stiffness after radiation, and obturators after maxillectomy.
Medically complex patients
Blood thinners, bone medications, diabetes, heart conditions, and transplants change how dental treatment is planned, and many Jacksonville patients have more than one of them. We review your medications and work with your physicians; read about complex and medically involved care and our physician referrals.
Oral medicine and diagnosis
Mouth sores that won’t heal, white or red patches, burning, and unexplained pain need a diagnosis, not a guess. Dr. Henley is a general dentist with advanced training in oral medicine; see oral medicine and diagnosis and our oral cancer screening.
Anxiety, children, and Spanish
Oral sedation is available for some anxious patients; ask whether it suits you, and read how we approach anxious patients. We see patients from age 2 to 102, including children, and Spanish is spoken in our office.

Your first visit
What a first visit looks like for a new Mandarin patient.
A standard new-patient visit is scheduled for about two hours: roughly an hour with Dr. Henley and an hour in hygiene, adjusted to what you need. You leave knowing what we found, what your options are, and the fee for anything we recommend. Emergency visits are shorter and focused on the problem.
Call and tell us why you’re coming
An implant consultation, a denture problem, a second opinion, or a toothache all start a little differently. Fill out our new-patient forms ahead of time to save time on the day.
History and exam with Dr. Henley
We review your medical history and medications, then do a comprehensive dental exam: teeth, gums, bite, old dental work, and an oral cancer screening.
Imaging when it’s needed
X-rays, photos, and, for implant planning, 3D cone beam imaging. We take what answers a question, not a fixed set.
A plan you understand
We explain the findings, the alternatives, and the order of treatment, with a written plan and fee before anything begins.
Cost and insurance
What will it cost, and do you take my insurance?
Fees depend on what you need: an emergency visit, a single implant, and full-arch implant teeth are very different. We give you the fee before treatment begins, so nothing is a surprise.
We are an out-of-network practice. Some dental plans cover part of implants, crowns, dentures, and emergency visits, often with a frequency limit. We can help you understand how to use your benefits; you are responsible for amounts your plan does not pay. Call our team with your plan details to ask about fees and payment arrangements.

Frequently asked questions
Questions from Mandarin patients.
Is your dental office in Mandarin?
No. Our office is in San Marco at 3675 Hendricks Avenue, Jacksonville, FL 32207, about 7 to 12 miles north of most of Mandarin on San Jose Boulevard. Many Mandarin patients come to us for implants, dentures, crowns and veneers, emergencies, and medically complex care.
How far is your office from Mandarin, and how long is the drive?
About 7 miles from Crown Point Road, 9.6 from Loretto Road, 10 from Mandarin Road, and 11.6 from the Mandarin Park area near Julington Creek. Without traffic that is about 13 to 22 minutes; allow more at rush hour on San Jose Boulevard.
Is there an emergency dentist near Mandarin that sees new patients the same day?
Yes. We see dental emergencies the same day during office hours, and new patients are welcome. Please call 904.398.1549 first rather than walking in, as early in the day as you can, so we can hold time for you and tell you what to do on the way from Mandarin.
What if I have a dental emergency at night or on a weekend?
Go to the ER for trouble breathing or swallowing, swelling spreading toward the eye or neck, fever with swelling, or bleeding that won’t stop. Existing patients can call or text our on-call line, 904.762.5616. New patients should use first-aid steps and call 904.398.1549 when we open. We don’t have weekend hours.
Will antibiotics alone fix a tooth infection?
Usually not. Antibiotics can calm spreading swelling, but the source, an infected nerve or a cracked tooth, is still there, so the infection tends to come back. The tooth needs treatment, such as a root canal, drainage, or an extraction. Swelling with fever or trouble swallowing needs the ER first.
Do you place dental implants, or do you send patients to a surgeon?
Dr. Henley places dental implants and restores them in our office, so one dentist plans the surgery and the final teeth together. That includes single-tooth implants, fixed full-arch implant teeth (All-on-X), and extractions with bone grafting. When a case is better handled by a specialist, we tell you and coordinate the referral.
Am I a candidate for dental implants?
Most healthy adults with enough bone, or bone that can be grafted, can have implants. Radiation to the jaws, some bone medications, uncontrolled diabetes, and heavy smoking raise the risk and change the plan. A comprehensive exam with 3D imaging shows the bone and lets us explain your options honestly.
How long do dental implants last?
A 2019 review of long-term studies found about 96.4 percent of implants still in place after 10 years. The crown or bridge on top can wear or chip and may need replacing sooner. Brushing, cleanings, not smoking, and a night guard if you grind all help implants last.
What is All-on-X, and how is it different from dentures?
All-on-X is a fixed arch of teeth held by several implants, usually four to six in a jaw. It is screwed in place, so it doesn’t move or come out at night, and an upper arch leaves the palate open. A denture rests on the gums and comes out for cleaning.
Can you fix my broken denture?
Often, yes, and denture repairs are one of the emergencies we see the same day during office hours. Bring every piece, and don’t use super glue or a drugstore kit, which make a proper repair harder. If the denture keeps breaking, we will look at why, because fit and bite are usually involved.
My denture is loose. What are my options?
The bone under a denture shrinks over time, so dentures loosen. Depending on your gums and bone, the answer may be a reline, a new complete or partial denture, a snap-in implant overdenture, or fixed full-arch implant teeth. We do all of these in our office and will explain which option fits you.
Do you redo crowns or veneers placed by another dentist?
Yes. Much of our cosmetic work is redoing veneers, crowns, and bridges that look bulky, opaque, or mismatched. We find the cause first, whether the bite, grinding, gums, or the design, and show you a preview before anything is replaced. A second opinion doesn’t commit you to treatment.
Who makes your porcelain veneers?
Our porcelain veneers are hand-layered e.max made by ceramist Paul Robert at Dynamic Dental Solutions, from a design you approve in a mock-up. Veneers usually take about three visits over about a month, which is a manageable schedule from Mandarin.
Do you treat patients going through head and neck cancer treatment?
Yes. Dr. Henley is a member of the Head and Neck Tumor Board at Baptist MD Anderson and sees patients before, during, and after radiation and chemotherapy. Ideally we see you about a month before treatment starts, so problem teeth can be dealt with first. Tell us your treatment dates when you call.
Do you offer sedation for anxious patients?
Oral sedation is available at our office for some anxious patients. Whether it is right for you depends on your health and medications, so we discuss it at your consultation. Many anxious patients also find that a longer first visit and a clear plan make the biggest difference.
Do you see children, and does anyone speak Spanish?
Yes to both. We see patients from age 2 to 102 as part of our general and family dentistry, so families from Mandarin can come together, and Spanish is spoken in our office. Se habla español.
Do you take my insurance?
We are an out-of-network practice and can help you understand how to use your benefits. Call our team with your plan details to ask about fees before scheduling. We give you the fee for any treatment before it begins.
Should I see you for routine cleanings if I live in Mandarin?
That is up to you. Many Mandarin patients make us their dental home, especially when they have implants, extensive dental work, or medical conditions we are already managing. Others do their implant, denture, or cosmetic work here and keep a dentist closer to home for routine cleanings. Either is fine with us.
Which Mandarin neighborhoods and zip codes do you serve?
We see patients from all of Mandarin, including Loretto, the Mandarin Road and St. Johns River neighborhoods, the area south toward Julington Creek, and along Old St. Augustine Road, in zip codes 32223, 32257, and 32258. We also see patients from San Jose, San Marco, Southside, and across Jacksonville and Northeast Florida.
