Many people notice brown or white spots on their teeth that don’t go away with brushing or whitening. These spots are usually caused by fluorosis, trauma, or early enamel changes. Dental microabrasion is a gentle, non-invasive treatment that polishes the surface of the teeth to remove these spots and restore a smooth, natural smile — without drilling, fillings, or injections.

Quick facts about microabrasion:

Best for brown spots, white spots, and superficial enamel stains
Quick and painless (one session, 30–60 minutes)
Permanent results once stains are removed
Works well alongside teeth whitening
More natural and cost-effective than fillings or veneers

What is Dental Microabrasion?

Microabrasion is a conservative cosmetic treatment that carefully polishes away surface stains and imperfections on the enamel. Instead of covering the problem, it reveals a fresh, smooth, and brighter surface of your natural tooth.

Unlike fillings or veneers, it doesn’t require drilling or the use of artificial materials — making it a safe and long-lasting option for a more even smile.

5 Situations Where Microabrasion is Recommended

Brown spots on teeth – Often caused by fluorosis, trauma, or developmental changes.
White spots after orthodontic treatment (braces) – Patches left behind where brackets were attached.
Mild fluorosis (chalky white or brown marks) – Discolouration from excess fluoride exposure.
Superficial stains from food, drinks, or smoking – When whitening alone isn’t enough.
Enamel defects from early trauma or development – Small irregularities or discoloured patches.

Key Benefits of Microabrasion (and Why It’s Better Than Fillings or Other Treatments)

Minimally invasive – No drilling, needles, or loss of healthy enamel.
Natural results – Works with your own enamel instead of covering it with fillings or veneers.
Immediate improvement – Brown and white spots can often be visibly reduced in a single appointment.
Permanent results – Once stains are removed, they don’t return.
Cost-effective and low-maintenance – No risk of chipping, staining at the edges, or needing replacement like veneers or fillings.

In short, microabrasion offers a safer, more natural, and longer-lasting solution compared to fillings, bonding, or veneers when the issue is superficial.

Tooth Protection – A barrier is placed to shield the gums.
Application of Microabrasion Paste – A gentle polishing paste is applied to the affected areas.
Repeat Applications – Fresh paste is applied and polished several times in one session for the best result.
Finishing Touches – The teeth are polished and treated with fluoride to strengthen and protect them.
