The short answer
A supernumerary tooth is an additional tooth beyond the usual number, and it is evaluated with an examination and dental imaging to see whether it affects nearby teeth.
Where can extra teeth develop and what forms can they take?
Extra teeth can occur in the front of the upper jaw, behind molars, or in other positions, and they may be erupted or buried in bone. A buried tooth can block eruption, displace neighboring roots, create a pocket for plaque, or remain an incidental finding.
How should you care for an erupted extra tooth meanwhile?
Keep regular brushing and cleaning around any erupted extra tooth, and bring prior dental images to the appointment. Do not try to loosen or remove it yourself because its position and relation to roots and nerves must be assessed first.
When should delayed eruption or an extra tooth be assessed?
Arrange an assessment if a tooth is delayed in erupting, crowded, painful, swollen, or found incidentally on an X-ray. Earlier evaluation may matter when a developing permanent tooth is being blocked.
What should you ask about monitoring or removing the tooth?
Where is the extra tooth, is it blocking eruption or damaging a root, and should it be monitored or removed? Ask which scan best shows its position and what treatment sequence is planned.
Frequently asked questions
Does every supernumerary tooth need removal?
No. The decision depends on its position, symptoms, effect on neighboring teeth, and the risks of observation or surgery.
Can an extra tooth stop a permanent tooth erupting?
It can obstruct the eruption path, so the dentist or orthodontist assesses the developing tooth and the extra tooth together.
