Teacup puppies begin teething around 20 days old. By 4-6 weeks, their deciduous (baby) incisors should be fully erupted. At 2-4 months, they'll start to lose their first set of incisors, followed by the second and third incisors and premolars between 5-6 months. By 8 months, all baby teeth should be replaced by permanent teeth. By 1 year, all permanent teeth are fully erupted. At 2 years old, the mandibular second incisor cusps may start to wear down. By 3 years old, the maxillary first incisor cusps will also begin to show wear. By the time the teacup puppy reaches 10 years old, the mandibular incisor wear will have created a longitudinal oval shape on the surface. From 11 to 20 years old, the incisors will start to fall out, and the canines may become uneven, eventually leading to total tooth loss.
Naturally bred teacup puppies typically have a lifespan of 10-20 years, directly related to their care and breeding methods. Their teeth undergo changes throughout their lives. A teacup puppy's dental development progresses through different stages. In the deciduous phase, they have 28 teeth: 12 deciduous incisors (6 upper and 6 lower), 4 deciduous canines (2 upper and 2 lower), and 12 deciduous premolars (6 upper and 4 lower). Between 3-7 months, they transition to their permanent teeth, comprising 40 teeth: 12 incisors (6 upper and 6 lower), 4 canines (2 upper and 2 lower), 20 premolars (10 upper and 10 lower) and 4 molars (2 upper and 2 lower). As teacup puppies age, their teeth gradually decrease in number and transition from white to yellow.
Dental Changes in Teacup Puppies From Puppyhood to Adulthood
1. At 1 year old, a teacup puppy's teeth are all fully erupted, very white, and sharply pointed.
2. By 2 years old, there may be minor plaque buildup. If not properly managed, significant tartar may develop.
3. Around 3-4 years old, you can clearly see tartar accumulation, and there may be debris in the gum line. The lower incisors might start to show wear or loosen.
4. By 5 years old, there will be significant tartar buildup, and tooth structure will begin to show signs of damage.
5. Around 7-8 years old, most teeth will likely be loose. The mandibular incisors will become rounded and may even start to fall out.
6. By 10 years or older, incisors will start to fall out. Therefore, proper dental care for teacup puppies is essential. Regular tooth brushing, professional dental cleanings, and dental chews can greatly improve their dental health, prevent periodontal disease, and ensure a happy and healthy life.
