Enamel Microabrasion
Enamel microabrasion is a minimally invasive cosmetic dental procedure used to reduce the appearance of white or brown discolourations on the enamel of teeth. The technique involves gently removing a very thin surface layer of affected enamel to improve the uniformity of tooth colour and surface texture.
This treatment is most effective for mild to moderate enamel defects and may be recommended after a thorough dental assessment.
Why Do White or Brown Spots Develop on Teeth?
White or brown enamel discolouration (also known as hypomineralisation) can develop for several reasons. In some cases, the exact cause is unclear, but contributing factors may include:
- White spot lesions following orthodontic treatment (braces)
- Early enamel demineralisation related to cavity formation
- Dental fluorosis caused by excess fluoride intake during childhood
- Certain antibiotics taken while teeth were developing (less common today)
- Trauma to a developing adult tooth before eruption
- Genetic factors affecting enamel formation
Symptoms of Enamel Hypomineralisation
The most common sign is the appearance of white spots, brown spots, or a combination of both on the teeth. These areas may appear patchy, irregular, or uneven in texture.
In most cases, the affected teeth are not painful; however, some patients may experience tooth sensitivity, particularly to cold food and drink. More severe cases may present with darker brown or grey banding across the teeth.
Is Enamel Microabrasion Suitable for Everyone?
Enamel microabrasion works best for surface-level enamel defects. In cases where discolouration extends deeper into the tooth, alternative treatments such as resin infiltration may be more appropriate and less invasive.
Your dentist will determine the most suitable option following assessment.
What Is Involved in Enamel Microabrasion?
Enamel microabrasion is only performed once your overall oral health is stable. In some cases, tooth whitening may be recommended prior to treatment. If whitening is completed, a waiting period of approximately two weeks is usually advised before proceeding with microabrasion.
The procedure typically involves:
- Isolating the teeth with a rubber dam to protect the gums
- Thoroughly cleaning the teeth
- Applying a specialised microabrasion gel containing a mild acid and fine abrasive particles
- Gently working the gel into the enamel using a rotating instrument
- Rinsing and repeating the process if required (usually 2–3 cycles)
- Polishing the treated enamel
- Applying a fluoride treatment to support enamel remineralisation and help with post operative sensitivity
Temporary tooth sensitivity may occur after treatment. Your dentist may recommend a desensitising toothpaste or topical remineralising agent to assist recovery.
Maintenance After Enamel Microabrasion
Once enamel microabrasion is completed, repeat treatment is usually not required. Long-term results are supported by good oral hygiene, including:
- Brushing twice daily with a fluoridated toothpaste
- Daily interdental cleaning with floss or interdental brushes
- Regular dental check-ups and professional cleans
If enamel sensitivity is present, a sensitive toothpaste or a CPP-ACP remineralising cream may be recommended.

Frequently Asked Questions
How Long Does Enamel Microabrasion Last?
Results are generally long-lasting, provided good oral hygiene is maintained and the discolouration was limited to the enamel surface.
Is Enamel Microabrasion Safe?
When performed on suitable cases, enamel microabrasion is considered a safe and conservative treatment. Temporary sensitivity is the most common side effect. Proper case selection is essential, as deeper stains may require alternative treatments.
How Much Does Enamel Microabrasion Cost?
The cost depends on the number of teeth treated, the size of the affected areas, and how many application cycles are required. A personalised cost estimate will be provided following clinical assessment.
