A gummy smile is when a noticeable band of gum shows above the upper teeth as you smile; many dentists consider it noticeable when more than about 3 to 4 mm of gum shows. It is not a disease and is mostly a cosmetic concern, but it has several possible causes. What matters is that treatment depends on the cause: it may be as simple as reshaping the gum line, or it may need orthodontics or a larger procedure.
There is no single cause, and more than one can be present in the same person. The main ones are:
Your dentist examines your smile at rest and when you laugh, and measures the length and width of the teeth, how much gum shows, and the length and movement of your lip. They may measure the depth of the gum around the teeth and take an X-ray to see where the bone sits under the gum. Photos also help with planning and discussing the options with you.
This step matters more than the treatment itself, because treating the wrong cause does not give a convincing result. For example, trimming the gum alone does not help if the main cause is an overactive lip, and injections do not help if the gum covers much of the tooth.
Your dentist chooses one treatment, or a combination, based on the cause, how marked it is and what you want:
When teeth look short because of the gum, placing veneers on them straight away can make them look wide and out of proportion. So in many cases the dentist reshapes the gum first, waits several weeks for it to heal and settle, and then designs the veneers with a more natural length and ratio.
In other cases, gum contouring alone is enough: the teeth show their true length without any veneers. Ask your dentist about this option before deciding to cover healthy teeth.
The procedure is usually done in one visit under local anaesthetic. Afterwards you may have mild soreness or sensitivity for a few days, and your dentist will advise what to take for it. Soft food is usually recommended, avoiding spicy and very hot food in the first days, and brushing gently around the area as instructed.
The gum heals initially in about one to two weeks, but its final shape takes longer to settle. Results vary between people depending on the gum type and the bone beneath, and in some cases the gum can creep back slightly over time, especially if the bone was not adjusted when needed.
Usually not; it is mainly cosmetic. But if it is caused by gum overgrowth or inflammation, there is a health issue that needs treatment before any cosmetic procedure.
It is done under local anaesthetic, and most patients feel mild discomfort for a few days afterwards that can be managed with painkillers recommended by the dentist. Experiences vary from person to person.
Slight regrowth can happen in some cases, especially if the bone sits very close to the gum edge and was not adjusted. Proper planning reduces this risk.
In the teenage years the gum may still be moving up naturally as the teeth finish erupting, so the dentist often prefers to wait, or to start with braces if needed.
See a dentist if your gummy smile bothers you or makes you avoid smiling, or if you notice your gums becoming larger, redder or bleeding easily, or changing after starting a new medicine. The first visit is only an assessment and does not commit you to any treatment. You can book a consultation at Medical Care Clinics in Al-Shati Al-Gharbi, Dammam, close to Al-Khobar and Dhahran, where our dental team will identify the cause and explain the options that suit you.
