What Your Dentist Checks Around Existing Fillings and Crowns
TL;DR
Your dentist checks existing fillings and crowns for changes in the restoration and nearby tooth, even when nothing hurts. The check does not mean either needs replacing.
- A filling’s age alone is not a reason to replace it; what happens next depends on the exam findings.
- A crowned tooth and the surrounding gums still need care. A visible change at the crown’s edge may need a closer look, but does not by itself establish decay underneath.
- An X-ray may help when the exam gives your dentist a reason to investigate, but it is not automatic and cannot detect every hidden problem.
- Tell your dentist about a loose restoration, new rough spot, food catching or discomfort rather than waiting for your next routine visit.
If a filling or crown does not hurt, you might wonder why your dentist checks it. A routine exam is a chance to look for changes that may not be causing symptoms. It does not mean the restoration needs to be replaced.
What gets checked around a filling?
Your dentist checks the filling and the surrounding tooth for signs of looseness, damage or decay. They also consider anything you have noticed, such as a change in how the tooth feels when you chew. The Canadian Dental Association identifies checking existing fillings as part of a dental exam.
A filling’s age alone is not a reason to replace it. If your dentist notices a change, what happens next depends on the examination findings—not simply how long the filling has been there.
What about a crowned tooth?
A crown covers a natural tooth; that tooth and the nearby gums still need care. Your dentist can examine the visible crown, where it meets the tooth and the gums around it. Brushing and cleaning between teeth remain important. Tell your dentist if the crown feels loose or food has begun catching in a new spot.
Looking at a crown cannot reveal everything beneath it. A visible change at its edge may call for a closer look, but it does not, by itself, establish that there is decay underneath.
When might an X-ray help?
Some areas are difficult to assess by sight. An X-ray may add useful information when your dentist has a clinical reason to investigate a tooth or an area beside a restoration. Health Canada advises that dental X-rays be based on a clinical examination, rather than taken automatically at every visit. Your dentist considers the image alongside the exam and your history; neither an X-ray nor a visual check detects every hidden problem.
Questions worth asking at your checkup
- Did you notice a change in this filling, crown or surrounding tooth?
- What can you tell from the exam, and would an X-ray add useful information?
- If no treatment is recommended now, when should we check this area again?
Let your dentist know about a loose restoration, a new rough spot, food catching or discomfort rather than waiting for your next routine visit. At Excel Dental in Hamilton, you can bring those questions to a general dentistry visit so the dentist can assess the tooth and discuss an appropriate next step.
