Teething in children?


Hello, Dr.
Tsai.
My daughter has been teething slowly; she only started getting her teeth after she turned one year old.
Now, at two years and two months, she has developed two upper canine teeth and the same number of lower teeth, but her upper canines have not yet erupted.
What should I do, doctor? Thank you.

Hello, Mr.
Amin's father: The growth of children's teeth can be influenced by many factors, including genetics, nutrition, calcium intake, and medications taken during pregnancy (such as Tetracycline).
However, it is unusual for your child to have their first tooth erupt after the age of one.
Generally, pediatricians consider tooth eruption after 13 months to be a pathological delay in eruption (Mean + 3 standard deviations).
A thorough examination is necessary to investigate the following potential causes: Is there hypothyroidism? How is the parathyroid function? Is there a family history of dental issues? Additionally, an oral X-ray assessment should be considered to check for any impactions, gingival fibromatosis, or even rare tumors (such as Histiocytosis X) or metabolic disorders (like Cyclin Neutropenia).
Therefore, if your child is already two years old, it is recommended that you take them to a pediatrician to evaluate for any thyroid and parathyroid issues, and also to a pediatric dentist for appropriate examinations.
It is important to increase the intake of calcium-rich foods (such as milk, lean meats, and small fish) and inquire about the developmental and medical history of family members.

Delayed tooth eruption in children can be a source of concern for many parents, especially when it seems that their child is not following the typical timeline for dental development. Generally, children begin to develop their primary teeth (also known as baby teeth) around six months of age, with a complete set of 20 teeth usually emerging by the age of three. However, variations in this timeline are common, and some children may experience delays without any underlying health issues.

In your case, your daughter began teething at over a year old and is now 2 years and 2 months with only a few teeth emerged. While this may seem concerning, it is important to remember that each child develops at their own pace. Factors such as genetics, nutrition, and overall health can influence the timing of tooth eruption.
Here are some steps you can take as a parent to address your concerns and support your child's dental health:
1. Consult a Pediatric Dentist: If you haven't already, schedule an appointment with a pediatric dentist. They can perform a thorough examination of your child's mouth and assess the development of her teeth. The dentist may take X-rays to determine if the teeth are present in the jaw and if there are any underlying issues that could be causing the delay.

2. Monitor Nutrition: Ensure that your child is receiving a balanced diet rich in vitamins and minerals, particularly calcium and vitamin D, which are essential for healthy tooth development. Foods like dairy products, leafy greens, and fortified cereals can help support dental health.

3. Maintain Oral Hygiene: Even if your child has only a few teeth, it's important to establish a routine for oral hygiene. Gently brush her teeth with a soft toothbrush and a small amount of fluoride toothpaste twice a day. This practice helps to prevent cavities and promotes healthy gums.

4. Be Patient: Delayed tooth eruption can sometimes resolve on its own. Many children who experience delays eventually catch up with their peers. If your child is otherwise healthy and developing normally, it may simply be a matter of time.

5. Watch for Other Symptoms: Keep an eye on your child's overall health and development. If you notice any other concerning symptoms, such as difficulty eating, persistent pain, or signs of infection (like swelling or fever), contact your pediatrician or dentist promptly.

6. Genetic Factors: Sometimes, delayed tooth eruption can be hereditary. If you or other family members experienced similar delays, this could be a normal variation for your child.

7. Follow-Up: If the dentist identifies any issues, such as missing teeth or other dental anomalies, they will provide guidance on the next steps. This may include monitoring the situation over time or discussing potential interventions if necessary.

In conclusion, while delayed tooth eruption can be worrying for parents, it is often a normal variation in development. Regular dental check-ups and good oral hygiene practices are key to ensuring your child's dental health. If you have any specific concerns or if the delay continues, don't hesitate to seek professional advice from a pediatric dentist. They can provide reassurance and guidance tailored to your child's unique situation.
