Best toothpaste to avoid root canal

Root canals are often necessary when decay reaches the pulp inside your tooth. But they can be expensive, uncomfortable, and time consuming. The good news is that preventing tooth decay and cavities in the first place through good oral hygiene is the best way to avoid a root canal. Your choice of toothpaste can play an important role.

Why Root Canals Are Needed

Root canal treatment involves deep cleaning out the root canal system inside your tooth, then sealing up the space. It is needed when bacteria cause infection and inflammation of the pulp. This often happens when a cavity is left untreated and decay reaches the pulp.

Cavities form when plaque buildup on your teeth releases acid that erodes tooth enamel. If the decay isn’t stopped, it progresses through the hard enamel into the softer dentin. Eventually it penetrates down to the pulp, which contains nerves and blood vessels. Infection and swelling of the pulp can be extremely painful and requires root canal treatment.

Key Toothpaste Ingredients to Prevent Decay

Certain ingredients in toothpaste can help strengthen enamel, reduce plaque, inhibit bacteria growth, and avoid cavities that lead to the need for a root canal. Look for these ingredients on your toothpaste’s label:

  • Fluoride – This fortifies enamel and prevents mineral loss in teeth. Fluoride helps reverse early decay by remineralizing weakened areas so cavities don’t form.
  • Xylitol – A natural sweetener that inhibits the S. mutans bacteria that are most responsible for causing cavities and tooth decay.
  • Tea tree oil – Contains antimicrobial compounds called terpenoids that fight tooth decay causing bacteria.
  • Clove oil – Another antimicrobial that’s been shown in studies to have cavity-fighting properties.
  • CoQ10 – This antioxidant protects gum tissue from inflammation and boosts the immune system against harmful bacteria.
  • Calcium – Along with phosphate salts, calcium strengthens weakened areas in enamel to prevent cavities.
