You likely have 31 teeth because one of your adult teeth may have never developed, or you may have had one extracted. It’s normal to have 32 permanent adult teeth, but variations do occur.
Missing Teeth: Understanding the Possibilities
Having fewer than 32 teeth is not uncommon. This can result from several factors:
- Congenitally Missing Teeth: Sometimes, teeth simply fail to develop. This condition is called hypodontia.
- Extraction: A tooth might have been removed due to decay, trauma, or orthodontic reasons. You might recall this happening even if it was long ago.
Factors Influencing Tooth Development
Several factors can contribute to missing teeth or incomplete tooth development, these include:
Genetic Predisposition
- Genes play a significant role in tooth development. If family members have missing teeth, you may be more likely to experience this.
Environmental Factors
-
Maternal Health: According to experts, advanced maternal age, low birth weight, maternal smoking, incidences of rubella, and other hormonal, environmental, and infectious conditions may also be linked to missing teeth.

Other Considerations:
- Dental Trauma: A past injury could have caused the loss of a tooth without you remembering the incident.
- Impacted Teeth: Sometimes a tooth might be present but fails to emerge from the gums, creating the appearance of a missing tooth. X-rays can reveal if this is the case.
What To Do If You're Concerned?
If you’re concerned about missing teeth or suspect an underlying issue, it's best to consult with your dentist. They can perform a thorough examination, take X-rays, and provide tailored advice based on your specific situation. They can also discuss options if you desire to replace the missing tooth for aesthetic or functional reasons.
