Retained Baby Teeth (Double Teeth)
If an adult tooth comes in next to a baby tooth that hasn't fallen out, see your vet soon. Toy and small breeds get this often.
Worth a vet check soon
Find an emergency vetWhat to do
- Check your puppy's mouth often from about 3 to 7 months old, as the adult teeth come in.
- Book a vet visit as soon as you see an adult tooth beside a baby tooth. Don't wait for the baby tooth to fall out.
- The usual treatment is removing the baby tooth under anesthesia, taking care to protect the adult tooth.
- If a spay or neuter is already booked very soon, your vet may do both together, but in most cases it's better not to wait for it.
Don't
- Don't try to pull out a baby tooth yourself.
- Don't wait months to see if it falls out on its own.
When to call your vet
- An adult tooth next to a baby tooth
- Two teeth in one spot, most often the fangs
- Crowded or crooked teeth
- Baby teeth still in place at 6 to 7 months
Why
A baby tooth that stays can push its adult tooth out of place within 2 to 3 weeks, causing a bad bite. Food also gets trapped between the crowded teeth, which leads to gum disease.
