20% Benzocaine: Benzocaine is a local anesthetic commonly used as a topical pain reliever or in cough drops. It is the active ingredient in many otc anesthetic ointments such as products for oral ulcers. It has been used prior to local anesthesia for dental work for years. Some experience a burning sensation when used, may be a type of allergy/contact dermatitis. Usually the longer on, the better it works.

A member asked:

Is it normal for bottom teeth to come in before top teeth?

11 doctor answers22 doctors weighed in
Dr. Scott Katz
Pediatrics 26 years experience
Yes: The bottom middle incisors are almost always the first teeth and usually come in around 7 months old. However it is not a concern if the top teeth come in first. If your child has no teeth at 15 months old, your pediatrician will likely recommend a dental visit.

What is a normal age to start losing teeth?

Dr. Robert Kwok
Pediatrics 33 years experience
6 years: Children lose their first baby teeth around age 6 years when the permanent teeth start coming in. They will get a total of 28 teeth (not counting any wisdom teeth). In the teen years, some kids have 2-4 teeth pulled before getting orthodontic braces. Years later, adults lose teeth through accidents, tooth decay, etc. . . The average number of remaining teeth at age 50-64 is 22-23 teeth.
