Cavities can be painful and lead to infections or other problems for your teeth. A dentist needs to properly fill the cavity to prevent these issues. This video shows how a dentist fills cavities, step-by-step.
When you first sit down in the chair, the dentist’s assistant may take your blood pressure and then inject an anesthetic. Next, they will apply a topical anesthetic to the tissue surrounding the tooth. There is a lot of attention paid to making sure you feel no pain during the filling.
They will then clean your mouth out with a rinse, and the dentist will get to work. The dentist uses a drill or laser to remove the decayed parts of the tooth. The dentist will then use a slower drill to ensure the removal of decayed parts.
To make sure there is no more damage to the tooth, the dentist will apply a cavity detecting solution to double-check their work. If everything is clear, the dentist will apply etch to the surface of the tooth to roughen the enamel.
The dentist will then layer on composite filling. Then an adhesive and bright light to harden everything together. The final step is to add resin and shape it to look like a tooth.
