This is the Life Cycle of your Teeth

Pediatric dentistry and primary teeth development.

Everyone knows the basics of pediatric tooth development. They grow in, fall out, grow back, and sometimes fall out again. Most people don't know that there is a system, and it starts months before that first little friend pops through the gum line. Teeth begin to develop in the embryonic stage at about 3-6 weeks, there the soft tissue forms and creates small translucent tooth nubs. At 3-4 months, hard tissue starts to develop around the tooth, and thin translucent roots will begin to grow down. By the time of birth, there are 20 fully developed teeth buried under the gums. In some rare cases, babies will be born with partially erupted teeth.

Baby's teeth will start to erupt between 3-6 months. Dentists colloquially call this stage teething. Since every child develops at a different rate, it's hard to say precisely when and what teeth will come in, fall out, and come back in. However, the first tooth to come in is typically the lower central incisor (middle teeth) between 3 and 6 months; and is shortly followed by the second lower central incisor.

Florida fact: In Boca Raton, around 4% of the population is under five years old.

Next is the upper central incisors, and they come in at around 8 and 12 months. Then the upper lateral incisors (next to middle teeth) at 9 and 13 months. After that, the top four molars come in between 13 and 25 months. Next, the lower lateral incisors at around 10 and 18 months. Then the lower four molars that come in between 14 and 23 months. The last to come in are the upper and lower cuspids (commonly known as canine) at around 16 and 23 months.

Now, when the baby teeth are ready to fall out the brain sends special cells to eat away at the baby tooth root. As this is happening the adult teeth are slowly starting to push the baby teeth up and out! While your baby teeth typically fall out in the order they erupt in, adult teeth are more sporadic. 

Permanent Teeth Upper:

Central Incisors: 6 to 7 years

Lateral Incisors: 8 to 9 years

Canine: 11 to 12 years

1st and 2nd Premolars: 7 to 11 years

1st and 2nd Molars:  8 to 12 years

Permanent Teeth Lower:

Central Incisors: 6 to 7 years

Lateral Incisors: 7 to 8 years

Canine: 9 to 10 years

1st and 2nd Premolars: 10 to 12 years

1st and 2nd Molars: 7 to 11 years

Sometimes permanent teeth can grow in crooked, this can be caused by:

  • thumb sucking
  • pacifier or bottle use
  • tongue thrusting
  • mouth breathing
  • misaligned jaw
  • having a baby tooth knocked out too early

These can cause jaw alignment issues, to fix these problems braces or other teeth alignment equipment may be used.

Once your permanent teeth come in they aren’t supposed to fall out. However, these factors commonly lead to tooth loss in adults:

Periodontitis: this is the main reason for almost half of tooth loss in America. Periodontitis works in stages. It starts off as gingivitis, an infection in your gums that causes redness, irritation, and deterioration of the tooth. At this stage, it can be reversed. The next stage is early periodontitis, this is when it becomes irreversible. Your gums start pulling away from your teeth, and harmful pockets of bacteria start to form. This bacteria then starts to eat away at the bone. That brings us to stage 3, moderate periodontitis which is the loss of bone structure along with the spread of bacteria from the gums to your bloodstream. The last stage is advanced periodontitis; this is when there is no more bone or tissue to support the tooth and root. Here you are at a very high risk for tooth loss and heart disease.

Cavities: they form when bacteria infection sits for too long and causes tooth decay. If the decay has reached the root a root canal is often necessary. If that fails the tooth will need to be extracted.

Injury: avoid using your teeth to remove caps, tops or lids, to loosen knots, tear off tags or cut thread. It’s also best to avoid using your teeth to chew ice, open nutshells, and crunch on popcorn kernels.

If your tooth falls out and is not cracked or broken, immediately put it in cold milk and call your dentist right away. We can sometimes reinsert the tooth. Do not attempt to put the tooth in yourself. It’s very easy to damage your gums forcing the tooth back in. This can also make it impossible to successfully reattach the tooth to the root by a professional.

Boca Raton dentist Dr. Polin has a solution for people that suffer from lost or failing teeth. 

The solution for lost or failing teeth is the dental implant. Implants are the best method to restore permanent function. Placing an implant creates an artificial titanium tooth root that fuses with the jawbone to support a color-matched crown.

Implants are the new standard of care for missing teeth, and also work with dentures. Dental Bridges: two crowns are placed on either side of the missing tooth with a false tooth in between, bridging the gap.

Dentures: upper and lower false teeth that you can take in and out. Technology has advanced over the last 40-years and these are not what your grandparents had. Dentures can be comfortable and even permanently secured with implants.

If you are a resident of Boca Raton and you are experiencing pain or swelling while brushing, call Polin Dental today to schedule an exam!

P.S. Remember to brush twice a day and floss at least once to keep your teeth clean and healthy.
