Tooth mamelons are small bumps on the edge of your front teeth. They usually appear on either two or four of your front teeth, with each tooth having a group of three bumps. They are a normal part of tooth development and are not problematic.
Typically, the wear down over time and do not require treatment. However, they may be cosmetically unappealing since they give your teeth are serrated or scalloped look.
Which teeth have mamelons?
Your permanent maxillary and mandibular incisors are where you will notice mamelons if you have them. They can form on both the central and lateral incisors, which are your four front teeth on either arch. More than 90% of people will see mamelons on their incisors when they erupt. However, they begin to wear down and become less noticeable or even completely disappear within just a few months of tooth eruption.
The mamelons appear on the incisal edge of the crown portion of your teeth. You'll notice a group of three, rounded bumps on the adult teeth that give them a wavy edge.
Baby teeth (also called primary teeth) never have mamelons.
Why do mamelons occur?
Mamelons are the result of healthy teeth formation. Teeth develop during pregnancy and mamelons are the result of the merging of different formation processes. They are actually formed on your permanent (adult) teeth before you're even born and help your teeth break through the gum tissue when it's time to do so.
How to remove mamelons?
If you don't like the way your teeth look due to the mamelons, your dentist can easily remove them by performing tooth recontouring or tooth reshaping. Their removal is a purely cosmetic procedure, although your insurance provider might pay for the treatment.
Your dentist will start by taking X-rays of your teeth to make sure it is acceptable to remove the mamelons. If they are too close to the dentin layer, the nerve, or there is decay, other procedures may be required.
Once your dentist has decided you can proceed, the procedure is quick. No local anesthetic is needed since it is only enamel being removed. Your dentist will use a reshaping bur to contour your teeth based on your gender and the shape of your other teeth. Once the mamelons are gone, they'll smooth and polish the enamel.
Oftentimes, if an adolescent undergoes orthodontic treatment, the orthodontist will simply remove the mamelons from incisor teeth when it's time to remove the braces. This is also a common treatment option in pediatric dentistry.
