Short answer: Gum problems in puberty arise because rising sex hormone levels increase blood flow in the gums and their reaction to bacterial plaque. The most common condition is puberty gingivitis, which involves red, swollen gums that bleed when brushing. In most cases it can be brought under control with regular, correct brushing, cleaning between the teeth and dental check-ups.
Puberty is a time of noticeable changes in the mouth as well as the body. During these years, many teenagers and families notice blood in the sink when brushing, or gums that look puffy or red. Gum problems in puberty are very common and are usually caused by increased sensitivity to bacterial plaque under the influence of hormones. The good news is that most of these problems can be reversed with proper oral care and regular check-ups.
In this article we explain why the gums become more sensitive during puberty, which symptoms need attention, what teenagers with braces should be careful about and when to see a dentist.
Why do gums become more sensitive in puberty?
In puberty, the gums become more sensitive because rising levels of estrogen, progesterone and testosterone widen the blood vessels in the gums and strengthen the tissue's inflammatory response to bacteria. The same amount of bacterial plaque can cause more noticeable redness and swelling than before puberty.
In dentistry, this condition is called puberty gingivitis. It usually becomes noticeable between the ages of 11 and 14 and tends to ease as hormone levels settle. However, this does not mean you should wait for it to go away on its own, because the real trigger of the problem is still the plaque building up on the tooth surfaces.
Once girls start menstruating, some may notice that their gums are more sensitive and bleed more easily in the days before their period. This fluctuation is also related to changes in hormone levels and often eases as the cycle progresses. Still, taking a little extra care with oral hygiene on these days helps keep the symptoms mild.
Besides hormones, there are other factors that can affect gum health during this period:
- Oral care slipping because of a busy school schedule and exam stress
- Increased consumption of sugary snacks, energy drinks and carbonated drinks
- Irregular sleep and eating
- Cleaning becoming harder because permanent teeth have just erupted or are crowded
- Mouth breathing, which can dry out and irritate the gums
- Smoking and e-cigarette use
What are the symptoms?
The most common symptom of gum problems in puberty is bleeding when brushing or flossing. Healthy gums look light pink, firm and matte; inflamed gums are redder, shinier and puffier.
The main symptoms to watch for are:
- Bleeding gums when brushing or biting into something hard
- Puffy, rounded-looking gum tips, especially between the front teeth
- Redness, tenderness or mild pain in the gums
- Bad breath that does not go away
- Yellowish, soft plaque buildup along the gum line
- Rarely, the gums growing to cover more of the teeth than usual
Although advanced gum disease is less common in teenagers than in adults, it can occur. If signs such as gum recession, loose teeth or marked bone loss are noticed, a detailed assessment should be done by a dentist.
Why do gums cause more problems for people with braces?
Gum problems are more common in teenagers with braces because plaque builds up more easily around the brackets and wires and cleaning becomes harder. Add the effect of puberty hormones, and the gums can easily swell and bleed.
To protect the gums during treatment with braces, the following is recommended:
- Brushing at an angle above and below the brackets after every meal
- Cleaning under the wires with interdental brushes or orthodontic floss
- Using aids such as a water flosser if your dentist recommends it
- Limiting sugary and sticky foods
- Keeping up with general dental check-ups for cleaning, in addition to orthodontic appointments
For some teenagers who struggle with oral hygiene, removable clear aligners may also be considered as an option in suitable cases. Because Invisalign aligners are taken out for eating and brushing, cleaning the teeth and gums is easier. However, the success of this method depends on wearing the aligners for 20–22 hours a day. For the differences between the two methods, you can read our article clear aligners or braces.
How should gums be cared for in puberty?
The foundation of keeping gums healthy in puberty is removing plaque buildup every day with the correct technique. Stopping or easing off brushing because the gums bleed is a common mistake; in fact, the bleeding areas need to be cleaned gently but regularly.
Daily routine
- Brushing at least twice a day for about two minutes with fluoride toothpaste
- Using a soft-bristled brush and making small circular movements at a 45-degree angle to the gum line
- Cleaning between the teeth once a day with floss or interdental brushes
- Replacing the toothbrush about every three months or when the bristles splay
- Gently cleaning the surface of the tongue as well
Lifestyle tips
- Choosing water instead of energy drinks and carbonated drinks
- Making oral care part of the nighttime routine, even during exam periods
- Staying away from cigarettes and e-cigarettes; these products increase the risk of gum disease and can mask its symptoms
- Eating a balanced diet with vegetables, fruit and enough protein
Mouthwash should only be used on a dentist's recommendation and for the stated period. Mouthwashes are no substitute for brushing and flossing.
What role do parents play?
Puberty is a time when young people start taking ownership of their own care routines, so the parents' role is to support rather than supervise. Constant reminders to brush can sometimes backfire. Instead, it is more helpful to have tools such as a suitable toothbrush and floss ready at home, to schedule regular dental appointments and to keep healthy snacks within reach.
It is also important for teenagers to share what they notice themselves. Complaints such as bleeding gums, bad breath or sensitivity often go unmentioned out of embarrassment. Explaining that these issues are normal and treatable makes it easier to seek help early.
When should you see a dentist?
You should see a dentist if gum bleeding lasts longer than two weeks, does not decrease despite regular brushing, or comes with swelling, pain and bad breath. In addition, an examination should not be delayed if there are loose teeth, gum recession, an inflamed bump on the gum, or mouth sores together with fever.
At the examination, the condition of the gums is assessed, tartar is removed if needed and a personal care plan is explained to the teenager. Most cases of this condition, which is common in teenagers, improve noticeably within a few weeks with professional cleaning and regular care at home. For teenagers having orthodontic treatment, the orthodontist and dentist work together.
At our clinic in Park Oran Ofis in the Oran neighborhood of Çankaya, gum care and orthodontic follow-up for teenage patients can be done together. For teenagers with gum complaints, the first step is a short examination to clarify the situation.
Frequently asked questions
Is bleeding gums normal during puberty?
Bleeding gums are common in puberty because of hormones, but this should not be accepted as normal and ignored. The real cause of the bleeding is usually bacterial plaque. If it does not go away despite regular brushing and cleaning between the teeth, you should see a dentist.
Should I stop brushing if my gums bleed?
No. Areas that bleed are usually areas where plaque builds up, and they need to be cleaned gently but regularly with a soft brush. With proper care, bleeding usually decreases within a few days to a few weeks.
Does puberty gingivitis go away on its own?
Symptoms may ease as hormone levels settle, but if plaque buildup continues, gum inflammation persists. For this reason, rather than waiting for it to go away on its own, it is recommended to improve oral care and go for a dental check-up.
What should I do if my gums swell while wearing braces?
The areas around the brackets need to be brushed after every meal and the space under the wires cleaned with interdental brushes. If swelling and bleeding continue despite regular care, you should let your orthodontist or dentist know; a professional cleaning may be needed.
