Why Do I See Small Gaps or ‘Black Triangles’ Between My Teeth After Braces?
Black triangles after braces are small spaces near the gumline that can appear when your teeth shift, gums recede, or bone support changes over time. While they may seem concerning, rest assured that these gaps are very common, completely treatable, and nothing to feel embarrassed about.
For personalized care, Dr. Mary Qian and her Palo Alto team specialize in advanced cosmetic and restorative solutions tailored to restore your smile’s natural harmony. With a patient-first approach and modern dental techniques, they’re here to help you achieve the confident, beautiful smile you deserve.
Why Do Black Triangles Appear After Braces?
Below, we’ll explore common causes of black triangles and what can be done to address them.
Gum Recession
After teeth are realigned, gums may shrink slightly, especially if there was preexisting inflammation or poor oral hygiene during treatment. This shrinkage can cause gaps to form, as the gum tissue no longer fills the space between teeth completely.

Tooth Shape
If teeth are triangular or slightly tapered, a space near the gumline can naturally appear once they are aligned. This is because the widest part of the tooth is closer to the biting surface, leaving less contact near the base.
Bone or Tissue Changes
Orthodontic treatment can sometimes alter the relationship between teeth, gums, and underlying bone. These subtle shifts can contribute to the appearance of black triangles.
Oral Hygiene Habits
Plaque buildup and gum inflammation during braces treatment can compromise gum health. Maintaining consistent oral care during and after braces is crucial to minimizing these effects. Regular flossing, brushing, and professional cleanings help support healthy, full gum tissue.
Are Black Triangles Harmful or Just Cosmetic?
While many patients first notice them for their appearance, black triangles can cause several issues, including:
- Food trapping, which can lead to discomfort and bad breath.
- Harder cleaning around the gums, increasing the risk of plaque buildup.
- An increased risk of gum irritation, which may contribute to sensitivity or inflammation.
Beyond aesthetics, these gaps can affect long-term oral health, as the difficulty in cleaning those areas may result in further gum recession or dental complications over time. Taking steps to address black triangles is about more than just restoring a confident smile. It’s also about maintaining a healthy one.

How to Fix Black Triangles After Braces
These spaces can occur due to gum recession or the natural shape of teeth. Fortunately, there are several effective ways to address this issue and restore your confident, healthy smile.
Dental Bonding
Using tooth-colored resin, dental bonding is a minimally invasive option to reshape teeth and close small gaps. This simple procedure blends seamlessly with your natural teeth, offering quick and effective results.
Veneers
For a long-lasting, natural look, custom porcelain veneers can be applied to the front surfaces of your teeth. Veneers not only close gaps but also improve overall aesthetics, creating a symmetrical, polished smile.

Gum Recontouring or Tissue Grafting
When black triangles are caused by gum recession, gum recontouring or tissue grafting can help. These procedures restore gum coverage, improving both function and appearance.
Orthodontic Retouching
Sometimes, minor tooth adjustments can reduce spacing and improve alignment. Orthodontic retouching is a targeted way to refine your smile and eliminate black triangles.
Preventive Care
Maintaining regular cleanings and practicing good home care are crucial. Preventive care helps ensure that black triangles won’t worsen over time and keeps your gums and teeth healthy.

Dr. Qian is responsive, precise, and goes the extra mile to keep patients comfortable.
