It is possible for cavities to form under existing dental fillings. It is important to have regular check-ups as you may be totally unaware of having such cavities.
Key takeaways:
– A damaged filling is vulnerable to penetration from bacteria which can create a new cavity under the filling.
– Due to wear and tear, fillings do not last forever and bacteria can get in under your filling again.
– Regular examination by a dentist can help prevent cavities forming under existing fillings.
“Filling materials can become damaged over time or worn out. Your filling does have a life expectancy depending on its material. For example, silver amalgam fillings have a life expectancy of 10-15 years while composite resin fillings have a lifespan of 5-7 years.”
