Tooth pain after a filling?
What’s normal, what’s not, and when to call.
Mild, brief tooth pain after a filling, especially sensitivity to cold, is common and often settles within one to two weeks. Pain that is getting worse, lingers after hot or cold, wakes you at night, or hurts when you bite is different, and deserves a call. You don’t have to wait two weeks to call.

Is it normal?
Is it normal for a tooth to hurt after a filling?
Mild, brief sensitivity can happen after a filling and often settles within one to two weeks. Some teeth take longer, particularly after deeper treatment. Improving sensitivity is different from sharp chewing pain, a bite that feels uneven, or pain that starts on its own.
You had the cavity treated. You expected the tooth to feel better. Now cold water catches your attention, chewing feels uncomfortable, or you are wondering whether you should call the office. That is a reasonable question.
The useful distinction is not simply whether the tooth hurts. It is what brings on the pain, how long it lasts, and whether it is improving. Call us if pain is worsening, lingering after hot or cold, or waking you at night.
Facial swelling, fever, or drainage needs urgent dental attention. Difficulty breathing or swallowing, or rapidly spreading swelling, requires emergency medical care.
Read the pattern
What your tooth pain after a filling may be telling you.
Short twinges to cold that fade in seconds and get better each day usually mean the tooth is settling. Pain when you bite down often points to a high filling or a crack. Pain that lingers after cold or heat, throbs on its own, or wakes you points to irritation inside the tooth that needs an exam. Symptoms alone can’t give a diagnosis, but they guide it.
| What you notice | Often suggests | What to do |
|---|---|---|
| A quick twinge to cold that fades in seconds, better each day | Temporary irritation as the tooth settles | Give it time; call if it isn’t improving |
| Pain when you bite, and the tooth seems to touch first | A high filling | Call for a bite check |
| Sharp pain on biting, or as you let go | A crack, or the filling’s bond | Call; tell us which it is |
| Cold or heat pain that lingers for a minute or more | Inflammation inside the tooth | Call promptly |
| Throbbing that starts on its own or wakes you | Inflammation that may not recover | Call promptly |
| Swelling, fever, a bad taste, or drainage | Possible infection | Urgent dental care today |
| A brief zap when metal touches the tooth | A small electric current between two different metals | Usually fades; mention it |
Pain can also be felt in a neighboring tooth, the ear, or the jaw, and sinus pressure can make upper back teeth ache; see sinus infection and tooth pain and reasons your tooth has been hurting.
Common causes
Why does a tooth hurt after a filling?
The most common reasons are temporary irritation of the nerve inside the tooth, a deep cavity that sat close to the pulp, a filling that changes how your teeth meet, and sensitivity related to the filling’s bond. Less often, the pain comes from a crack, from grinding, or from a different tooth altogether.
Temporary irritation inside the tooth
The pulp is the living tissue inside your tooth, containing nerves and blood vessels. Decay and dental treatment can irritate it. When that irritation is reversible, the tooth may be briefly sensitive while it settles.
A deep cavity close to the pulp
A filling repairs the damaged part of the tooth, but the pulp’s ability to recover depends on its condition. Deep decay can cause more significant inflammation, and a tooth may need further treatment if that inflammation doesn’t resolve.
A filling that changes how your teeth meet
If the new filling contacts the opposing tooth too soon, biting may hurt. You may notice that the treated tooth seems to touch first. This is a reason to have the bite checked, not something you should feel obligated to tolerate.
Sensitivity related to the filling’s bond
Tooth-colored composite shrinks slightly as it hardens. Shrinkage stress and problems at the bond between the filling and tooth can contribute to sensitivity. Symptoms alone can’t tell you whether this is the cause; the restoration needs to be examined. Read more about tooth-colored fillings.
A crack in the tooth
Teeth with large old fillings often have cracks that a new filling doesn’t fix. Sharp pain on biting or on release is the classic sign. See cracked or chipped tooth.
Clenching or grinding
Night-time clenching loads every tooth, and a freshly treated one can feel bruised. If your jaw is tired in the morning, read about teeth grinding (bruxism).
Sore gums or a tender jaw for a day or two are common too, from the clamp, the injection, or holding your mouth open. If you are still numb, see how long dental numbness lasts.
A high filling
Why a high filling deserves a prompt bite check.
When you call, tell us whether the tooth seems to hit before the others. That detail helps us understand what you are experiencing. If the filling is high, the dentist can reshape it to improve how your teeth meet.
An adjustment may be straightforward, but we wouldn’t promise that every painful filling needs only a quick polish. A bite check is a starting point, not a diagnosis. Sharp pain may also come from a crack or a problem inside the tooth. Pain that continues after an adjustment deserves reassessment.
Being numb during the visit makes it hard to feel your bite exactly, which is one reason a filling can feel high once the numbness wears off.
Do not try to file down the filling yourself.
What comes next
Does pain after a filling mean I need a crown or root canal?
Not automatically. These treatments address different problems. Some teeth need both; others need neither. The recommendation should follow the examination, not simply the fact that the tooth hurts.
A crown
A crown may protect a tooth that has lost substantial structure or has certain types of cracks. It supports the remaining tooth during chewing. Our explanation of why a tooth may need a crown covers how that decision is made, and dental crowns and bridges covers the options.
A root canal
A root canal treats inflamed or infected tissue inside the tooth when that tissue can’t recover. A crown alone doesn’t remove infected pulp. Root canals on front teeth and premolars are usually done in our office; most molar root canals are referred to an endodontist we work with.
A crack
A crack can cause pain during chewing or as biting pressure is released. Its location and extent affect the treatment options, and not every cracked tooth can be saved.
Nothing more
Often the right answer is time, a bite adjustment, or a desensitizing step. When a crown is recommended, we walk you through the next steps before anything is scheduled.
When should I call the dentist?
When to call about tooth pain after a filling.
Call promptly for a bite that feels high, repeated chewing pain, lingering temperature pain, spontaneous throbbing, or pain that disrupts sleep. Worsening symptoms deserve attention on any day; there is no reason to wait until day three.
- Call promptly: a high bite, chewing pain, lingering hot or cold pain, throbbing, or pain that wakes you.
- Request urgent dental care: swelling, fever, drainage, or severe pain. Our emergency dental care page explains how to contact the office; we see emergencies the same day during office hours.
- Call 911 or go to an emergency department: difficulty breathing or swallowing, swelling spreading into the neck or around the eye, or rapidly increasing facial swelling. Don’t wait for an online appointment response.
you have facial swelling, fever, drainage, or severe pain. Call us at 904.398.1549; for difficulty breathing or swallowing, or swelling spreading toward the neck or eye, go to an emergency department. See emergency dental care and tooth abscess.
While you wait
What can I do at home for tooth pain after a filling?
Choose softer foods, avoid chewing on the painful tooth, and limit very hot or cold foods that trigger symptoms. Keep the area clean with gentle brushing. These measures may make you more comfortable, but they don’t replace a needed examination.
Do
- Chew on the other side and choose softer foods for a few days.
- Brush gently with a soft brush; a toothpaste for sensitive teeth may help mild cold sensitivity over a couple of weeks.
- Follow your individual home-care instructions.
- Note what triggers the pain and how long it lasts, so you can tell us.
Avoid
- Chewing before normal sensation returns if you are still numb.
- Very hot, very cold, or very sweet foods that set it off; see foods to avoid with sensitive teeth.
- Filing, picking at, or adjusting the filling yourself.
- Waiting out pain that is getting worse.
Pain medicine may help temporarily when it is safe for you. It won’t correct a high bite, repair a crack, or resolve every cause of dental pain. For more on why teeth get sensitive, read the biggest causes of tooth sensitivity.
A careful evaluation, not a rushed assumption
How we evaluate a tooth that still hurts after a filling in Jacksonville.
When a tooth remains uncomfortable, the next step is to understand why. The evaluation may include checking the filling and bite, testing how the tooth responds to cold or gentle pressure, and taking an X-ray when appropriate. It is the same approach we take at a comprehensive dental exam.
At our Jacksonville practice in San Marco, we want you to feel comfortable telling us when something doesn’t feel right. We will listen, explain what we find, and discuss the options without pressure. Dr. CJ Henley sees every patient himself, so the dentist who placed your filling is the one who checks it.
Had your filling done elsewhere? We are happy to take a look. Patients come to 3675 Hendricks Avenue from Southbank, San Jose, Riverside, Avondale, and Downtown, and from Mandarin, the Southside, and the Beaches.
You should not have to decide on your own whether your pain is “normal.”
Frequently asked questions
Questions about tooth pain after a filling.
How long should a tooth hurt after a filling?
Mild, improving sensitivity often settles within one to two weeks, and some teeth take a few weeks, especially after a deep filling. Pain that is getting worse, lingers after hot or cold, or wakes you is worth a call at any point.
Can a filling fail in a week?
Yes, an early problem is possible, but sensitivity alone doesn’t prove that a filling has failed. Call if a piece breaks off, the filling feels loose, or symptoms are worsening. An examination can distinguish a restoration problem from irritation inside the tooth.
Why does my tooth hurt when I bite down after a filling?
The filling may be interfering with your bite, but a crack or pulp problem is another possibility. Tell your dentist whether pain occurs as you bite, as you let go, or both. That pattern helps guide the examination.
Why is my tooth sensitive to cold after a filling?
Brief cold sensitivity is common while the nerve settles, especially after a deeper filling or a tooth-colored bonded filling. If it fades in seconds and improves each day, it is usually settling. Cold pain that lingers for a minute or more needs an exam.
Can I take ibuprofen after a filling?
Ibuprofen can help with dental pain for adults who can take it safely. Follow the label or your clinician’s instructions. Check first if you are pregnant, take blood thinners, or have kidney disease, a history of stomach ulcers or bleeding, or an allergy to anti-inflammatory medicines. Acetaminophen may be an alternative for some people; ask about safety if you have liver disease, and don’t exceed the labeled dose.
Is a high filling an emergency?
A high filling by itself generally needs a prompt dental appointment rather than a hospital visit. Don’t keep chewing through pain or try to adjust it yourself. Severe pain, swelling, fever, or breathing or swallowing difficulty changes the urgency.
My tooth still hurts after two weeks. Should I call?
Yes. Some sensitivity can last several weeks, but persistent symptoms are worth discussing rather than continuing to guess. Call sooner for worsening pain, a changed bite, lingering temperature pain, or pain that starts without a trigger.
Why does a different tooth hurt after my filling?
Dental pain can be referred, so a sore tooth can feel like its neighbor or a tooth in the opposite jaw. The injection site, a sore jaw from holding your mouth open, or a tooth that was already irritated can also be the source. An exam sorts it out.
Do I need a root canal if my tooth hurts after a filling?
Not automatically. Most teeth settle. A root canal is needed only when the tissue inside the tooth can’t recover, which shows up as lingering or spontaneous pain, and tests at the exam help tell the difference.
Why do I feel a small shock when my fork touches the filling?
Two different metals in the mouth, such as a metal filling and a fork or a gold crown, can create a tiny electric current. It is usually brief and fades over time. Mention it at your next visit.
