Anbesol vs Orajel – Which Works Better For Canker Sores or Toothache?

Anbesol vs Orajel – Which Work Better For Canker Sores or Toothache

Canker sores are shallow lesions which develop on the soft tissues in the mouth. Canker sore symptoms include:

  • a tingling sensation in the mouth;
  • a painful red area in the mouth;
  • a small yellow or white oval-shaped ulcer in the mouth.

Below is a comparison of two over-the-counter oral health care products:

Anbesol

It contains benzocaine, a medicine which is mainly useful for topical application.

Benzocaine is part of a family of medicines called local anesthetics that helps numb the area it is applied to.

Orajel

It is an OTC medicine whose active ingredient is benzocaine, which is used to relieve mouth pain.

Unlike slower acting oral analgesics, its topical application works by directly targeting the source of pain.

Bottom Line – Anbesol vs Orajel: Which Is Better For Canker Sores And Toothache?

Anbesol is an over-the-counter medicine that is used to relieve pain associated with canker sores, cold sores, and toothaches. It contains as the main ingredient – benzocaine.

Contraindicated for teething pain and use in children younger than 2 years due to the risk for methemoglobinemia.

Orajel is a topical pain reliever. It contains as the main ingredient – benzocaine, a topical anesthetic that numbs the part of the human body it touches by blocking nerve signals which are telling the brain that you should be in pain.

According to the data, both over-the-counter oral health care products are a good solution for patients to temporarily relieve them of pain if they experience a canker sore or a toothache.

Both have the same active ingredient (benzocaine) and the difference lies in their inactive ingredients, brand name, and price.
