Mamelons are those little bumps you sometimes see on the biting edges of brand-new, permanent front teeth. They usually show up as three distinct bumps on each incisor.
Mamelons of teeth are normal in kids and teens, and they usually mean that the teeth developed as they should.
This article will explore mamelons, how they develop, what causes them to stick around, potential problems they can cause, and how they’re usually managed.
How do mamelons form, and what’s their purpose?
Mamelons appear during tooth formation, when separate lobes of enamel come together to create the biting edge of the incisor.
Some dentists believe mamelons are there to help the tooth erupt, or break through the gumline. But the real purpose of these tiny cusps may be to tell the dentist or dental hygienist about the overall health of the tooth.
The presence of mamelons may indicate that the enamel formed correctly. They’re also a sign that the tooth grew and developed naturally.
Natural disappearance and persistence
Mamelons are usually a temporary feature of newly erupted teeth. But sometimes, they stick around.
Typical timeline for disappearance
In most kids, mamelons gradually wear away from typical chewing and tooth-to-tooth contact.
Mamelons tend to disappear sometime in the late teens or early twenties.
Reasons for persistence in adults
Softer foods, genetic factors, and even diligent tooth care can cause mamelons to stick around into adulthood.
Because today’s diets tend to be lower in roughage, there’s often less tooth wear, which means that mamelons are more likely to persist.
Genetics may also play a role in whether mamelons hang around. Some people are simply more likely to have them.
And ironically, good dental hygiene may play a part. If you’re brushing and flossing carefully and regularly, there’s less friction and wear on the edges of your incisors.
Potential issues and when to seek treatment
Mamelons are not usually a cause for alarm, but in some situations, they can cause problems or prompt a visit to the dentist.
Aesthetic concerns
For some adults, mamelons can be a cosmetic issue. The little scallops on the biting edge of the teeth may be distracting and cause some people to feel self-conscious.
Functional and sensitivity problems
In rare cases, mamelons can interfere with a person’s bite. The uneven edges can also contribute to tooth sensitivity in some people.
When to consult a dentist
It’s always a good idea to consult with your dentist if you have concerns about your teeth. If you’re bothered by the look of mamelons or if they’re causing problems with your bite or sensitivity, it’s time to make an appointment.
Any unusual wear patterns on your teeth should be assessed by a dentist.
Treatment options for mamelons
If you’re an adult and you’re bothered by the appearance of mamelons, there are a few cosmetic dentistry procedures that can help smooth them out and make them less noticeable.
Cosmetic dental procedures
- Enamel recontouring. This is a straightforward procedure to smooth and reshape the edges of your incisors.
- Dental bonding. A dentist can apply a composite resin to give your teeth a smoother, more even appearance.
- Veneers. For a completely new look, thin porcelain shells can be bonded to the front of your teeth.
Considerations for treatment
Most dentists prefer to start with minimally invasive procedures, such as enamel recontouring, before moving to veneers or other more involved treatments.
Together, you and your dentist can decide on a treatment plan that fits your dental health, your budget, and your aesthetic preferences.
Key Takeaways
Mamelons are a normal, harmless variation in tooth shape. If you have them, there’s usually nothing to worry about.
However, if you’re not happy with the way your teeth look or if the mamelons are interfering with your bite, talk to your dentist. They can advise you on the best course of action.
Whether you have mamelons or not, remember that good oral hygiene and regular dental checkups are essential for healthy teeth and gums.
