Cavities are common, even when people have strict dental hygiene regimens. Plaque can still build up in hard-to-reach areas and, over time, cause tooth decay. Depending on the stage of decay, the cavity can be treated with either a filling or a root canal. By learning more about your treatment options, you'll be better prepared if a cavity forms. 

How Do Tooth Fillings Treat Cavities? 

In its early stages, a cavity remains small and likely undetectable without a dental exam. The level of decay is minute, allowing for a filling to be placed in the affected tooth. While the procedure's steps somewhat vary depending on the type of filling and the location of the cavity, they'll most likely include:

  • Apply a numbing gel to the gums along with a local anesthetic. 
  • Use a drill to remove the decay from the affected tooth. 
  • Fill the hole with a tooth-colored composite resin or amalgam to prevent bacterial infections.
  • Polish and adjust the filling so that the patient's bite isn't negatively affected. 

There may be minor soreness or sensitivity after the anesthetic wears off. Over-the-counter medications, like acetaminophen and ibuprofen, can help relieve the discomfort. 

How Do Root Canals Treat Cavities? 

Root Canal

Cavities don't cause toothaches immediately, especially if they're closer to the surface than the root. However, as the decay worsens or if the cavity forms closer to the root, a filling will no longer be an effective treatment. Instead, patients will need a root canal. 

While the procedure is more invasive, modern root canals don't cause significant physical distress. Most of the discomfort felt after the treatment can be relieved by the same O.T.C. medicines as a filling. During the root canal, dentists will:

  • Administer a local anesthetic to numb the affected tooth and cover the area with a small sheet to prevent saliva from reaching the tooth. 
  • Open the crown of the tooth to remove the decay and the infected pulp. 
  • Reshape part of the pulp chamber to fill the area with a bio-compatible material that takes the pulp's place and seal the chamber with dental cement.
  • Add a temporary filling to protect the tooth from food particles and debris until you're ready for a permanent filling or a specially-molded crown.

The filling or crown acts as a regular tooth and needs the same hygiene process to remain healthy. Remember to brush twice daily with fluoride toothpaste, use floss, and return to the dentist for exams as needed.
