Supernumerary teeth:
- What are supernumerary teeth?
- teeth which appear in addition to the regular number of teeth
- the most common supernumerary teeth are the maxillary incisors and first premolars
- adult dogs should have 42 adult teeth
- What causes supernumerary teeth?
- extra adult tooth buds
- Can extra teeth appear for other reasons?
- Deciduous teeth are the first teeth a puppy gets. Sometimes they fail to leave when the adult teeth erupt.
- Tooth gemination happens when one adult bud tries to split into two. The result in one tooth which appears to have two crowns.
- Odontomas are tumors that happen when a tooth is forming. They create small unusually shaped teeth.
- What effect do these teeth have?
- crowding, rotation and displacement of teeth which predisposes to periodontal disease
- How is it diagnosed?
- Step 1: count the teeth
- Step 2: take dental radiographs even if there are 42 adult teeth; sometimes extra teeth are impacted
- How is it treated?
- If the extra teeth are likely to cause periodontal disease then the offenders should be extracted.
- If no adverse effects are likely then no treatment is needed.
