A dentist will often apply a filling once a cavity has been removed. However, there are still times when another cavity can form. Why might this problem occur? Let us take a look at some (surprisingly) common situations.
– A recent filling has become cracked or otherwise damaged.
– The filling is quite old.
– Fillings which are too large could allow food and bacteria to enter.
“Although dental fillings are designed to seal your tooth and protect your teeth, no dental filling material lasts forever.”
