As children grow, their baby teeth fall out and make way for permanent teeth. While this is a natural process, parents often wonder how to best care for their child’s new teeth. Since permanent teeth are meant to last a lifetime, establishing good oral hygiene habits early is essential.

At The Kids Dentist of Henderson, we help parents understand everything they need to know about permanent teeth, from when they come in to how to keep them healthy.

When Do Permanent Teeth Come In?

Children typically begin losing baby teeth around age six. By age 12 or 13, most will have all their adult teeth, except for the wisdom teeth.

Here’s a general timeline for permanent tooth eruption:

• First molars: 6-7 years
• Central incisors (front teeth): 6-8 years
• Lateral incisors: 7-9 years
• Canines (cuspids): 9-12 years
• Premolars (bicuspids): 10-12 years
• Second molars: 11-13 years
• Wisdom teeth (third molars): 17-25 years

During this period, children go through a mixed dentition phase, where they have both baby and permanent teeth. Some teeth may appear crooked at first, but they often shift into place as more permanent teeth come in. If misalignment persists, an orthodontic evaluation may be recommended.

Why Are Permanent Teeth Important?

Permanent teeth play a crucial role in chewing, speech, and maintaining facial structure. Since they do not naturally fall out like baby teeth, keeping them healthy is essential. Without proper care, permanent teeth can develop decay, gum disease, and other oral health issues that can last into adulthood.

Caring for Permanent Teeth

Good oral hygiene should begin as soon as permanent teeth emerge. Parents can help by encouraging the following habits:

• Brushing at least twice a day with fluoride toothpaste.
• Flossing daily to remove plaque between teeth.
• Limiting sugary snacks and drinks that contribute to cavities.
• Visiting the dentist every six months for cleanings and checkups.

Common Problems with Permanent Teeth

Several issues can affect permanent teeth, including:

Tooth Decay – Cavities form when plaque and bacteria erode tooth enamel. Brushing, flossing, and regular dental visits help prevent this.

Gum Disease – Gingivitis can cause redness, swelling, and bleeding. If left untreated, it can lead to more serious gum infections.

Crowding and Misalignment – Some children may not have enough space for their permanent teeth, leading to crowding or bite issues. An orthodontic evaluation can help determine if treatment is needed.

Tooth Sensitivity – Some children experience discomfort when eating hot, cold, or sweet foods. A dentist can recommend solutions such as fluoride treatments or sensitivity toothpaste.

Orthodontic Considerations

As permanent teeth emerge, some children may develop alignment issues. Signs that orthodontic treatment may be needed include:

• Crooked or overlapping teeth
• A noticeable overbite or underbite
• Difficulty chewing or speaking
• Early or late loss of baby teeth affecting permanent tooth spacing

An orthodontic evaluation is often recommended around age seven to monitor development. In some cases, early intervention can prevent more serious issues later.

The Importance of Mouth Guards for Sports

Sports injuries are a leading cause of dental trauma in children. Wearing a mouth guard can help protect permanent teeth from being chipped, broken, or knocked out.

Mouth guards are especially important for contact sports like:

• Football
• Basketball
• Soccer
• Baseball
• Hockey
• Martial arts

Custom-fitted mouth guards provide the best protection and comfort compared to store-bought options.

Wisdom Teeth Removal Around Age 16

Wisdom teeth, or third molars, are the last permanent teeth to emerge, typically between ages 17 and 25. However, many people do not have enough space in their mouth for these teeth to come in properly, leading to problems such as:

• Pain and swelling
• Crowding of existing teeth
• Impacted wisdom teeth (teeth that don’t fully emerge)
• Increased risk of infection and cavities

A pediatric dentist and orthodontist can work together with an oral surgeon to determine the optimal time for wisdom teeth removal. In many cases, removing wisdom teeth around age 16 is ideal because the roots are not fully developed, making the procedure easier and recovery faster.

When to Visit the Dentist

Regular dental checkups every six months help maintain oral health by detecting issues early. Parents should also schedule an appointment if their child experiences:

• Tooth pain or sensitivity
• Visible cavities or discoloration
• Persistent bad breath
• Bleeding or swollen gums

Sealants and fluoride treatments can provide additional protection against cavities, especially for back molars where decay is most common.

Losing Permanent Teeth and What to Do

Permanent teeth do not grow back if they are lost. Losing a tooth due to decay, injury, or gum disease can lead to shifting teeth, difficulty chewing, and bone loss in the jaw.

If a permanent tooth is knocked out:

• Pick up the tooth by the crown, not the root.
• Rinse it gently with water if dirty, but do not scrub it.
• Try to place it back into the socket and have the child bite down on gauze.
• If reinserting isn’t possible, store the tooth in milk or saliva and seek emergency dental care immediately.

For missing teeth that cannot be saved, dental implants or bridges may be recommended to restore function and appearance.

Encouraging Lifelong Healthy Habits

Parents play a key role in their child’s long-term oral health. Encouraging proper brushing, flossing, and a balanced diet helps keep teeth strong. Drinking water instead of soda or juice and limiting sugary foods can significantly reduce the risk of cavities.

Conclusion

Permanent teeth are meant to last a lifetime, making early care essential. By establishing good oral hygiene routines, ensuring regular dental visits, and taking steps to protect teeth from injury, parents can help their children maintain strong, healthy smiles.
