A tooth that aches after a filling: normal or a problem?

A tooth can feel sensitive after a filling, particularly with hot, cold or sweet foods, or when you bite your teeth together. But that does not mean every ache should be left alone. Healthdirect advises seeing your dental professional again if the tooth is still sensitive after a few days.

If the discomfort is getting worse or is not settling, contact Woonona Dentists rather than assuming it is part of recovery. Our tooth-coloured fillings information gives the same advice: call if sensitivity does not settle or gets worse.

Having just had a tooth repaired, it can be frustrating to need to ask about it again. You do not need to work out the cause before calling. Tell us when the filling was placed and what you are noticing; ask whether you should return for an assessment.

What sensitivity can happen after a filling?

Healthdirect describes sensitivity to sweet foods, hot or cold foods, and biting the teeth together after a filling. It also lists short-term sensitivity among the risks of a filling. This is a possible response, not a prediction about how your own tooth will feel.

For the decision about when to get help, the useful point is not a promise that it will settle by a set day. If sensitivity continues after a few days, arrange another dental visit. If it worsens, contact the clinic rather than waiting for that point.

What if it hurts when I bite?

Biting sensitivity can occur after a filling, but pain when biting is also a reason Healthdirect gives for seeing a dentist about toothache. Tell the team specifically that biting hurts, rather than describing the tooth only as “sensitive”.

Note whether a drink, sweet food or closing your teeth together brings on the discomfort. Say whether it comes and goes or is there without a trigger. A dentist may examine your mouth, ask about your dental and medical history and take an X-ray if needed to find the cause.

You can also explain if your teeth seem to meet differently since the appointment. Ask the dentist to assess the tooth and your bite; this article cannot tell you whether a filling needs an adjustment or a different treatment.

When should I call sooner?

Do not use the “few days” advice as a reason to wait through worsening symptoms. Our fillings page asks you to contact us if discomfort gets worse. For toothache that lasts more than two days or does not improve with pain-relief medicines, Healthdirect advises seeing a dentist as soon as possible.

• Tell a dentist about fever, trouble swallowing, pain when biting, a bad taste, or swelling of your cheek or jaw.
• Get emergency medical care for trouble breathing or speaking, or swelling around your eye or neck. For urgent medical help, call triple zero (000).

A recent filling does not change those warning signs. For more detail on urgent symptoms, read our toothache guide or the emergency dental care page.

What can I do while arranging advice?

Follow the aftercare instructions given for your own tooth. For temporary care while arranging dental treatment, Healthdirect suggests foods that are easy to chew and swallow, avoiding very hot or cold drinks, and cleaning with a soft toothbrush and fluoride toothpaste. These measures do not replace assessment of a sore tooth.

If you need pain relief, ask your doctor or pharmacist what is suitable and follow the packet instructions. Mention your other medicines and health conditions when asking for advice. Tell the dentist what you have taken and whether it helped.

Does a temporary filling change the plan?

A temporary filling can be used when treatment needs more than one session, for emergency care, or to protect a tooth between root canal appointments. It is replaced with a lasting filling to complete treatment. Ask what your next appointment is for and when it should happen; temporary does not mean the work is finished.

If part of a filling breaks off or the whole filling falls out, see your dental practitioner as soon as possible. Better Health Channel gives this advice even though fillings can also wear out gradually over time.

Will the filling have to be replaced?

Not every sensitive tooth needs the same response. Healthdirect says treatment for toothache depends on its cause. A filling, crown, root canal treatment or removal of a badly infected tooth are among the possible treatments, not recommendations for your tooth based on this article.

Fillings can chip or crack over time and allow food and bacteria to become trapped. Your dental professional can advise whether an old filling needs replacing. That is different from assuming a newly filled tooth needs another procedure because it is sensitive.

Before agreeing to further care, ask what the examination found, which options suit the tooth, and what the benefits, risks and alternatives are. Woonona Dentists explains that you can ask for a pause or decline proposed treatment after discussing the options and risks. Our treatment choices article can help you prepare.

What should I tell Woonona Dentists?

• When and where the filling was placed, and whether it was temporary.
• What triggers the discomfort and whether it is improving, unchanged or worsening.
• Whether biting hurts, and any swelling, bad taste, fever or swallowing difficulty.
• Any medicines you have used and any relevant medical conditions.

Call (02) 4284 4486 and ask about a review appointment and any assessment fee. You can use our contact page for clinic details or read Dr Beena Kurian’s profile. There is no need to choose a treatment before your tooth has been checked.
