Dental fillings restore the strength and function of a tooth after decay but they don’t last forever. Overtime, fillings can wear down, crack, or loosen, leading to discomfort or new decay. If you’re noticing sensitivity, pain when chewing, or dark spots near a filling, it’s worth getting it checked.
At John Street Dental, our independent dentists can assess and replace worn or damaged fillings. Whether it’s an older amalgam or composite restoration, we’ll restore your tooth with a durable, natural-looking result
Why Replace a Filling?
-
Wear and tear: Chewing or grinding can weaken fillings.
-
New decay: Bacteria can form around worn edges.
-
Cracks or chips: Pressure or temperature changes can damage fillings.
-
Aesthetic upgrades: Swap metal fillings for tooth-coloured composites.
The Process
At John Street Dental Clinic, replacing a filling is simple: the old filling and decay are removed, the tooth is cleaned, and a new filling is placed and polished for comfort.
If you think your filling needs attention, book an appointment with one of our independent dentists at John Street Dental or call our friendly staff on 3284 4281 if you have any questions or concerns.
