Hypodontia

Hypodontia is a condition where some teeth never develop, so they are missing.

There are different terms depending on how many teeth are missing:

• Hypodontia
  One or a few teeth are missing (more common).
• Oligodontia
  Many teeth (six or more) are missing.
• Anodontia
  All teeth are missing (very rare).

Sometimes, the teeth that do grow can be smaller than usual.

How common is it?

• It affects a small number of baby teeth.
• It is more common in adult (permanent) teeth.

Why does it happen?

Hypodontia often runs in families, so it can be inherited. It may affect females slightly more than males.

The teeth most often missing are:

• Wisdom teeth.
• Upper side front teeth (lateral incisors).
• Lower premolars (back teeth near the front).

How is hypodontia diagnosed?

Your dentist can usually spot missing teeth during an examination.

They may take dental X-rays to check which teeth are present and which have not developed.

You might be referred to a specialist, such as an orthodontist, for further advice.

What treatment is available?

Treatment depends on:

• How many teeth are missing
• Where the gaps are
• Your age
• How your bite and smile are affected

Options may include:

• Braces (orthodontics) to move teeth into better positions
• Bridges or dentures to replace missing teeth
• Dental implants as a long-term fixed replacement (when suitable)

Sometimes a baby tooth that has not fallen out can be reshaped or covered with a crown or veneer to improve how it looks.

What should I do?

Talk to your dentist about the best options for you.

Always ask for:

• A written treatment plan.
• A clear estimate of the costs.

Early advice can help plan the best long-term result for your teeth and smile.
