Journey of a Tooth

Everyone knows the basics of tooth development, they grow in, fall out, grow back and sometimes fall out again. What most people don’t know is 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 start 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, this stage is commonly called teething. Since every child develops at a different rate it’s hard to say exactly 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. 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 upper 4 molars come in between 13 and 25 months. Next the lower lateral incisors at around 10 and 18 months. Then the lower 4 molars that come in between 14 and 23 months. The last to come in are the upper and lower cuspids (commonly known as canine) come in 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, some of these factors can cause you to lose adult teeth:

  • Periodontitis: Commonly known as gum disease is responsible for 70% of tooth loss. It is an infection in your gums that causes redness, irritation, deterioration of the tooth, and finally tooth loss.
  • Cavities: They form when bacteria infection sits for too long and causes tooth decay. If the decay has reached the root a root canal must be done, if that fails the tooth will need to be pulled.
  • Injury: Avoid using your teeth to remove caps, tops or lids, to loosen knots, tear off tags or cut thread, don’t use your teeth to chew ice, open nut shells or chew 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. The dentists can sometimes reinsert the tooth. Please do not attempt to put the tooth in yourself, you can cause damage to your gums. This can make it impossible for the dentist to successfully reattach the tooth to the root.

There are a few different ways to repair your smile after the loss of a tooth. Ask your dentist which option is best to replace those missing teeth.

Remember to brush twice a day and floss once to keep those pearly whites clean and healthy.

Here’s The Definition Of A True Dental Emergency

What is a dental emergency? If you feel pain, call! You don’t want it to get worse than it already is.

Also, getting a tooth knocked out is an emergency too! If this ever happens, the sooner you get to the dentist the better chance of your tooth being saved.

Did you know over 5 million teeth get knocked out every year! Whether it’s sports related or accidental. Speaking of sports, with the Stanley Cup and NBA playoffs are going on, don’t try to mimic your favorite moves without using a mouth guard.

Prevention is Key!

It’s summer, a good time to learn a new sport or play in leagues. Any contact sport is best played with a mouth guard. You never know what to expect, an elbow to the mouth, falling to the floor, unable to catch your fall and a ball/puck to your mouth. A mouthguard can’t protect you sitting in your gym bag! Discuss with your dentist which option is the best for your activities.

What To Do If Your Tooth Gets Knocked Out

When your tooth is knocked out, other things are in danger as well. Nerves, blood vessels, and tissues can also be damaged from the trauma. After it’s been knocked out, you want to pick it up by the crown and not the root. Rinse the tooth gently, but not the root because you could be scrubbing away the periodontal ligament or the cementum which is important to hold your tooth in the socket. Soap and chemicals are damaging to the cells remaining on the root and will most likely make the tooth impossible to reattach and save.missing tooth.png

Another thing you can try is putting the tooth back in the socket. Sounds weird right? But it can help keep the tooth moist, giving it a better chance to be reattached. Another option to try is to leave it in a cup of milk because of the biological compatibility and low bacteria count, the milk can help preserve the tooth.

The most important thing to do is to call your dentist office ASAP! Your dentist will be able to determine if your tooth can return to full function or not. The longer you put off the dentist the higher the risk of permanent tooth loss If your tooth cannot be saved, your dentist will go over dental bridge and implant options.

Dental Emergency vs. True Dental Emergency

Is there a difference? Absolutely! Not to confuse you, but in both scenarios, you should see your dentist regardless! Let’s clarify the difference and explain anything that is unclear.

Signs of a True Dental Emergency

  • Tooth Loss
  • Extreme Pain
  • Tooth Abscess or Pus
  • Swelling
  • Cracked or Chipped toothpain.png

Losing an “adult” tooth is a dental emergency and needs quick action to save the tooth. With pain you should call your dentist, especially with extreme pain that doesn’t lessen or go away with over the counter medicine. That could be a sign that something more significant is wrong. Pus is a sign of infection and you could need antibiotics. It’s important to get treatment right away to help the pain and infection go away. If left untreated a tooth abscess may lead to continuous dental problems. If you see swelling on your gum line or jawline it can also be a sign of an infection. Cracked or a chipped tooth is one of the most common dental emergencies. A cracked tooth exposes your nerves, which can cause more pain and if left untreated, the crack may get worse resulting in tooth loss.

Things happen and can’t be controlled, but it’s important to be able to identify what’s wrong. If you notice any of these symptoms, it’s important to see your dentist right away.

You can never plan for a dental emergency, but you can always have your bi-annual cleanings scheduled and our number saved in your phone!
