What Is Macrodontia and Microdontia: Alteration of Tooth Size

March 17, 2026 • By Dr. Megha Sheth

Many people have teeth that are larger or smaller than normal — and may not even realize it's a diagnosable condition. At Planet Family Dental in Lynnwood, WA, Dr. Megha Sheth evaluates tooth size abnormalities and offers cosmetic and restorative solutions to help patients achieve a balanced, confident smile.

✅ Key Takeaway

Macrodontia (abnormally large teeth) and microdontia (abnormally small teeth) are tooth size conditions that can affect your smile's appearance and function. Dr. Sheth at Planet Family Dental can diagnose these conditions and recommend treatments like veneers, bonding, or crowns to restore balance.

What Causes Tooth Size Abnormalities?

To achieve a balanced smile, all the components of your mouth must be in harmony — the shape of your lips, the size of your jaw, and the proportions of your teeth. People naturally have teeth of different sizes and shapes, usually proportional to their jaw size. But some individuals have teeth that are noticeably larger or smaller than normal.

These conditions can be genetic, related to developmental factors, or associated with certain syndromes. Dr. Sheth uses digital X-rays and a thorough clinical exam to diagnose tooth size abnormalities at Planet Family Dental in Lynnwood, WA.

Macrodontia vs. Microdontia — Understanding the Difference

Macrodontia (Large Teeth)

Teeth that are considerably larger than normal for the jaw. This can cause crowding, overlapping, and difficulty with bite alignment.

Can affect one tooth (partial) or all teeth (generalized). More common in the upper front teeth and premolars.

Microdontia (Small Teeth)

Teeth that are considerably smaller than normal. This creates gaps between teeth and can affect the overall appearance of your smile.

Partial microdontia (affecting one or a few teeth) is the most common type. Often affects the upper lateral incisors, which may appear peg-shaped.

Treatment Options at Planet Family Dental in Lynnwood, WA

The treatment depends on the type and severity of the condition. Dr. Sheth evaluates each case individually and may recommend:

Porcelain Veneers

For microdontia, porcelain veneers can make small teeth appear normal-sized, closing gaps and creating a uniform smile.

Dental Bonding

Dental bonding adds composite resin to build up small teeth — a quick, affordable option for mild cases.

Dental Crowns

For macrodontia or severely misshapen teeth, dental crowns can reshape and resize teeth for a more proportional appearance.

Clear Aligners

For crowding caused by macrodontia, clear aligners can reposition teeth for better alignment without traditional braces.

When to See Dr. Sheth About Tooth Size in Lynnwood, WA

If you or your child has teeth that appear unusually large, small, or disproportionate, Dr. Sheth can evaluate the condition and discuss your options. Many patients don't realize treatment is available — and the results can be transformative for both appearance and confidence.
