Frequently Asked Questions

Answers from CJ Henley, DMD, on cosmetic dentistry, dental implants, preventive care, and dental care before and after cancer treatment. Our practice is located in San Marco, Jacksonville, Florida.

My approach is to listen carefully, preserve healthy teeth when possible, and explain your options clearly. These answers provide general guidance; your recommendations depend on an examination and your dental and medical history.

How often should I see the dentist if I don’t have pain? Regular care based on your risk, not just your symptoms

Cavities, gum disease, and other dental problems can develop without pain. Many patients have preventive visits about every six months, but that is not the right schedule for everyone. I recommend an interval based on your gum health, cavity history, dry mouth, medical conditions, and home care. Patients with active disease or higher risk may need more frequent visits.

What should I expect at my first appointment with Dr. Henley? Time to discuss your concerns, examine carefully, and understand your options

Your first visit includes a review of your dental and medical history, an oral health evaluation, and X-rays when needed. We discuss your concerns, explain our findings, and review appropriate next steps without pressure. New patient appointments are typically scheduled for about two hours. Bring your current medication list and let us know about relevant medical treatment, previous dental difficulties, or anxiety before your visit.

Do I really need dental X-rays? Imaging is selected to answer a clinical question

Dental X-rays can reveal decay between teeth, bone loss, and problems around tooth roots that a visual examination may miss. They do not show every problem, including every tooth fracture. The type and timing of imaging should depend on your examination, symptoms, dental history, and disease risk, not an automatic schedule. When suitable previous images are available, we review them before deciding whether additional imaging is needed. You can see the equipment we use, typical radiation doses, and our full safety protocol on our digital and 3D imaging page.

Can dental X-rays increase cancer risk? Low-dose imaging with a clear reason for each examination

Dental X-rays use ionizing radiation and carry a small potential risk. With appropriately selected imaging, the expected diagnostic benefit generally outweighs the small radiation risk. Exposure varies by the examination; a small dental X-ray and a three-dimensional cone-beam CT scan are not equivalent. I recommend imaging only when clinically justified, using the appropriate technique and limiting exposure while obtaining the information needed for your care.

What’s the difference between composite bonding and porcelain veneers? Two ways to improve a smile, with different preparation and maintenance needs

Composite bonding uses tooth-colored resin shaped directly on a tooth to repair chips, close selected gaps, or refine its appearance. Porcelain veneers are custom-made shells bonded mainly to the front surfaces of teeth to change their color, shape, or proportions. Veneers are not full-coverage crowns. Bonding can often preserve more tooth structure and is generally easier to repair; porcelain is more stain-resistant. Neither changes color with teeth whitening, so if you want lighter teeth, whiten first. The choice depends on your enamel, bite, goals, and maintenance expectations.

Will cosmetic dentistry damage my natural teeth? Preserving healthy tooth structure while explaining irreversible changes

Some cosmetic treatments require little or no tooth reduction; others permanently remove enamel. Porcelain veneers usually involve some preparation, and crowns generally require more extensive reshaping. These changes are not reversible, and sensitivity or future repair can occur. My goal is to choose the least invasive option that can reasonably meet your needs. We discuss alternatives, limitations, and long-term maintenance before changing healthy teeth.

Can veneers or crowns that look unnatural be improved? Evaluate the shape, color, fit, and bite before deciding on replacement

Often, yes. Bulky contours, mismatched color, excessive opacity, or proportions that do not suit your smile can make dental work look unnatural. The first step is to evaluate the restoration, the underlying tooth, your gums, and your bite. Some concerns can be addressed with adjustments or repairs; others require replacement. The goal is a natural-looking result that also supports healthy tissues and comfortable function.

How long do veneers, bonding, and crowns last? Long-term results depend on the restoration and the patient

These restorations can serve patients for many years, but none should be considered permanent or maintenance-free. Longevity depends on the amount of healthy tooth remaining, material selection, fit, bite forces, oral hygiene, and cavity risk. Grinding, dry mouth, and untreated gum disease can complicate maintenance. Bonding may need polishing or repair, while veneers and crowns may eventually need replacement. Regular reviews help identify problems early.

Are dental implants safe? A useful tooth-replacement option with benefits and risks to consider

Dental implants are an established option for replacing missing teeth in appropriately selected patients. They are not risk-free: complications can include infection, failure to integrate with bone, and injury to nearby structures. Planning includes evaluating bone, gums, medical history, medications, and the intended final restoration. We also discuss alternatives and the ongoing care needed to maintain the implant and replacement tooth.

Why do some dental implants fail? Early healing problems and later disease require different evaluation

An implant may fail to integrate with the bone during healing or lose support later. Peri-implantitis is inflammation around an implant with loss of supporting bone. Smoking, poorly controlled diabetes, a history of gum disease, and difficulty keeping the area clean can increase risk. A loose crown or screw is not necessarily a failed implant. Careful planning and maintenance reduce risk, but not every complication is preventable.

Is a dental implant better than a bridge? The best option depends on your neighboring teeth, health, and priorities

An implant can replace a missing tooth without using neighboring teeth for support and may help limit local bone loss. A conventional bridge relies on adjacent teeth and can be appropriate when those teeth already need crowns or when surgery is less suitable. We compare bone availability, medical risks, treatment time, cleaning needs, and cost. Neither option is automatically best for every patient.

Do dental implants last forever? Long-lasting does not mean maintenance-free

Implants can last for many years, sometimes decades, but lifetime success cannot be guaranteed. The implant in the bone and the crown, bridge, or denture it supports have different maintenance needs. Restorations can wear or fracture, and screws can loosen even when the implant remains stable. Daily cleaning and professional monitoring are essential. Report pain, bleeding, swelling, or movement rather than waiting for your next routine visit.

Does full-mouth rehabilitation mean removing all my teeth? Comprehensive reconstruction can include preserving natural teeth

No. Full-mouth rehabilitation is a coordinated plan to restore health, function, and appearance when problems affect much of the mouth. Depending on your needs, treatment may combine restorations on natural teeth, periodontal care, and replacement of missing teeth. It does not automatically mean extracting every tooth or placing implants throughout the mouth. I evaluate which teeth can be predictably maintained and explain the tradeoffs before recommending irreversible treatment.

What does medically informed dental care mean? Your medical history is part of the dental treatment plan

Medically informed dental care means considering how your health conditions, medications, and previous treatments affect dental decisions. At our practice, that includes planning for patients with cancer-treatment histories, dry mouth, and other medical complexities, not only individual teeth. When necessary, we coordinate with your physicians and dental specialists. Read more about medically complex dental care. The aim is to choose appropriate treatment, timing, and prevention for your circumstances rather than use the same plan for everyone.

I’ve had radiation or chemotherapy. Is dental work different for me? The type of treatment and the tissues involved make a difference

It can be, but chemotherapy and radiation do not carry identical dental risks. Chemotherapy can affect the mouth, blood counts, infection risk, and healing, particularly during active treatment. Head and neck radiation can cause lasting dry mouth and changes in jawbone healing when those tissues receive radiation. Tell us what treatment you received, where it was directed, and when. We may need oncology records or medical coordination before planning care.

Do I need a dental evaluation before head and neck radiation? Identify dental risks early and coordinate care with your oncology team

Yes. A dental evaluation before head and neck radiation helps identify infection, advanced decay, gum disease, and teeth unlikely to remain maintainable after treatment. We also plan preventive care for possible dry mouth and increased cavity risk. Not every patient needs extractions. The dental plan depends on your findings, anticipated radiation exposure, and cancer-treatment schedule. Contact us as soon as radiation is being planned so any necessary dental care and healing can be coordinated without unnecessary delay to cancer treatment.

Can I have a tooth extraction or dental implant after head and neck radiation? Previous radiation to the jaw requires a specific risk assessment

Sometimes, but surgery in previously irradiated jawbone requires careful planning. Radiation can increase the risk of osteoradionecrosis, a condition in which damaged jawbone fails to heal and areas of bone die. Risk depends on the dose and location of radiation, the procedure, and your oral and medical health; it can persist long after treatment ends. We review relevant records and coordinate with your oncology team and an oral surgeon when appropriate. There is no single waiting period that makes surgery safe for everyone.

Why does dry mouth increase my risk of cavities? Less saliva means less natural protection for your teeth

Saliva helps clear food, neutralize acids, and supply minerals that protect teeth. Persistent dry mouth, or xerostomia, can increase decay risk, including around fillings and crowns, and can contribute to oral discomfort and fungal infections. Causes include medications, Sjögren’s disease, and radiation involving the salivary glands. Depending on the cause, care may include prescription-strength fluoride, saliva-support products, dietary changes, and closer follow-up. Do not stop a prescribed medication without discussing it with your clinician.

Can I get dental implants if I have diabetes, autoimmune disease, or osteoporosis? A diagnosis alone does not determine implant eligibility

Many patients with these conditions can receive implants, but suitability depends on disease control, medications, gum health, and healing capacity. Poorly controlled diabetes or significant immune suppression can increase complications. Osteoporosis alone does not automatically rule out implants, but some medications used to treat it require additional discussion. We assess your individual risks and coordinate with your physician when needed before deciding whether implant treatment is appropriate.

Can Fosamax, Prolia, or other bone medications affect dental treatment? Medication type, dose, and reason for treatment matter

Yes. Bisphosphonates such as alendronate (Fosamax) and medicines such as denosumab (Prolia or Xgeva) can increase the risk of medication-related osteonecrosis of the jaw. This complication is uncommon with osteoporosis treatment, while higher-dose regimens used for cancer generally carry greater risk. Tell us about current and past use before extractions, implants, or other bone surgery. Do not stop or delay medication on your own; treatment decisions should be coordinated with the prescribing clinician. Routine preventive dental care remains important.

What mouth or throat symptoms should I have checked for oral cancer? Persistent changes deserve evaluation, even when they do not hurt

Have a mouth sore that lasts more than two weeks, a persistent red or white patch, an unexplained lump, or ongoing numbness evaluated. A neck lump, persistent hoarseness, or difficulty swallowing also warrants medical or dental attention. Many changes are not cancer, but persistent or worsening symptoms should not wait until your next cleaning. An examination can identify concerning findings, but screening cannot rule out every cancer. A biopsy or specialist referral may be needed.

Should I replace old silver fillings with tooth-colored fillings? The condition of the tooth and filling matters more than the color

Not automatically. The FDA does not recommend removing intact amalgam fillings solely to prevent disease. Unnecessary replacement removes additional tooth structure and temporarily increases mercury exposure during removal. Decay, a broken filling, a tooth fracture, or a documented material sensitivity may justify replacement. If a recently replaced filling is uncomfortable, see tooth pain after a filling. Recommendations for placing new amalgam are different: alternatives are encouraged for certain higher-risk groups, including pregnant or nursing patients, young children, and people with impaired kidney function, neurological disease, or allergies to amalgam components. We discuss tooth-colored options when treatment is appropriate.

Does fluoride toothpaste help prevent cavities? A preventive tool tailored to your age and cavity risk

Yes. Fluoride toothpaste helps strengthen enamel and repair early mineral loss, reducing the risk of cavities. Brushing twice daily with an age-appropriate amount is a standard preventive recommendation. Patients with dry mouth, frequent decay, or other elevated risks may benefit from additional topical fluoride recommended by a dentist. More is not always better: follow product directions, supervise young children, and avoid swallowing toothpaste. Your prevention plan should reflect your individual needs.

Do I really need a deep cleaning, or scaling and root planing? Treatment for periodontitis, not a routine upgrade to a cleaning

Scaling and root planing treats periodontitis, a form of gum disease that damages the tissues and bone supporting teeth. The recommendation should be based on a periodontal examination, including pocket measurements, attachment loss, bleeding, and X-ray findings when needed. Bleeding alone does not establish the need for deep cleaning. Treatment removes bacterial deposits below the gumline and is followed by reassessment and a maintenance plan. Ask us to explain the findings that support your diagnosis.

Is dental treatment painful, and what if I’m anxious? Clear communication and a comfort plan before treatment begins

Our goal is to keep treatment as comfortable as possible. Local anesthesia controls pain during many procedures, although you may still notice pressure or vibration, and some soreness afterward can be expected. Tell us about anxiety, previous difficulty getting numb, or a difficult dental experience. We can discuss breaks, explain each step, and adjust the approach to your needs. Let us know immediately if you feel pain during treatment.

What should I do about severe tooth pain or facial swelling? Know when to call the dentist and when to seek emergency care

Severe tooth pain, new swelling, a knocked-out permanent tooth, or a dental injury needs prompt assessment. For milder discomfort after recent treatment, our guide to tooth pain after a filling explains what is normal, what is not, and when to call. Call our office at 904-398-1549 for guidance rather than relying on text for an urgent problem. Trouble breathing or swallowing, rapidly spreading swelling, or swelling near the eye requires immediate emergency care, call 911 or go to an emergency department. Do not wait for an office reply when these symptoms are present. Dental infections can become serious even if the pain temporarily improves.

Why doesn’t dental insurance always cover the recommended treatment? Plan benefits and clinical recommendations answer different questions

Dental coverage depends on your plan’s contract, exclusions, frequency limits, and annual maximums. A treatment may be clinically appropriate even when it is not covered or when the plan pays only toward an alternative. I explain the diagnosis, reasonable options, and expected benefits so you can make an informed decision. Confirm your specific benefits and estimated out-of-pocket responsibility before treatment; coverage should inform the discussion, not replace it.

How should I compare dental treatment plans and costs? Compare the diagnosis, alternatives, and full scope, not just the fee

A lower fee does not automatically mean poor care, and a higher fee does not guarantee a better result. Ask which teeth need treatment, why each procedure is recommended, what alternatives exist, and what the estimate includes. For extensive care, discuss maintenance, possible future repairs, and whether treatment can be staged safely. The goal is a plan you understand that fits your clinical needs, priorities, and budget.

Will you ever recommend monitoring instead of treatment? Yes, when observation or prevention is clinically appropriate

Yes. A stable finding may be better managed with prevention and scheduled reassessment than with immediate treatment. Monitoring is an active plan: we explain what we are watching, when to review it, and what changes would make treatment necessary. It is not appropriate for every problem, especially an active infection or a suspicious lesion. My goal is the right amount of care, not the most treatment.
