How Do I Know if I Have a Cavity? Tips from a Chippewa Falls Dentist

Can a cavity heal on its own without a filling?

A cavity can only be reversed in its very earliest stage, known as de-mineralization, before a physical hole forms in the enamel. Once acid creates an actual hole in the enamel, the damage is permanent and cannot heal on its own. At that point, a dentist must clean out the bacteria and place a filling to restore the tooth.

How long can you leave a cavity untreated before it gets severe?

Leaving a cavity untreated is risky because decay constantly spreads deeper into the tooth. While decay can move slowly over several months in thick enamel, it spreads much faster once it reaches the softer dentin layer underneath. Delaying treatment leads to larger fillings, root canals, or even tooth loss.

Does getting a tooth filling hurt?

No. Dentists use local numbing medicine to ensure the tooth and surrounding gum tissue are completely numb before starting any work. You might feel mild pressure during the procedure, but you should not feel pain. Temporary mild sensitivity after the numbing wears off is normal and resolves quickly.

Why do I have a cavity even though I brush my teeth every day?

Brushing is essential, but it might not reach every deep groove on chewing surfaces or tight spaces between teeth where plaque builds up. Genetics, dry mouth, dietary choices, frequent snacking, or irregular flossing habits can also contribute to cavity formation despite daily brushing.

How often should I get checked for cavities?

Most children and adults should receive a routine dental examination and professional cleaning every six months. Regular visits allow your dentist to spot early signs of decay when treatments are easiest, least invasive, and most affordable.
