Why sharks don’t get cavities – A lesson in fluoride

/in , /by

Sharks have the healthiest teeth in the animal kingdom. That’s pretty impressive seeing as sharks average around 15 rows of teeth in each jaw. Some sharks end up growing and shedding up to 30,000 teeth in their lifetime. Great pearly White Shark, that’s a lot of teeth! How do sharks keep all their teeth looking so porcelain and clean? Well for one, they don’t drink a lot of sugary beverages or candies. It also turns out that sharks have a fluoride coating on their teeth. In fact, their teeth contain 100% fluoride.   Makes sense that they would have their own type of travel toothpaste since they always seem to be on the move.

Why is fluoride so important?

Fluoride is an active ingredient in most toothpastes and is even added to water throughout the country. It’s extremely important in fighting against tooth decay. It protects teeth by restoring the loss of minerals on the tooth enamel. When our teeth lose those minerals on the enamel, it opens the doors to cavities. Think of fluoride as a protective shield, keeping acids that eat through the tooth’s surface at bay. If plaque and tartar are allowed to accumulate on teeth for an extended period of time, it can allow for dangerous bacteria to grow next to the gums. By getting routine teeth cleanings harmful build is removed from your tooth and leaves the tooth surface smooth and clean in order to stop bacteria from developing.

 

How to make sure you are getting enough fluoride:

  • Fluoride is a naturally-occurring mineral and is found in various foods and water.
  • Mouthwashes and toothpastes often contain fluoride. Your dentist may even apply higher doses of fluoride in a gel or foam form when you have a checkup.
  • Sometimes a doctor may decide that you need a fluoride supplement. These are available in liquid or tablet form.
  • Fluoride is also important for adults – It’s important to continue to use fluoride toothpaste even after the ‘formative years’ for teeth
  • Too much fluoride can be a bad thing. Knowing how much your city puts in water is important.

 

It just doesn’t seem fair that a mammal with thousands of replaceable teeth also has the advantage of never getting cavities. Throw a dog a bone! Unfortunately, humans can’t regenerate teeth each time we get a new cavity, so remember to brush and floss daily because this is the only real set of teeth you’ll have!

What to do if your tooth is knocked out

/in /by

Your first reaction if your tooth is knocked out might be to freak out, cry, flail your arms and tell yourself life is over (speaking from experience).

Do not do that – Unless you are a famous hockey player who wears this empty tooth slot like a badge of honor. Everything will be fine.

Modern dentistry has come along way and if you act quickly it will increase the likelihood of saving the tooth.

Dental implantThe upper front permanent teeth are the most common teeth to be completely knocked out. Baby teeth are usually not reimplanted in the mouth after an injury, since they are replaced naturally by permanent teeth later. When a tooth is knocked out, the nerves, blood vessels and supporting tissues are damaged, too. The nerves and blood vessels can’t be repaired. That is why all avulsed teeth will need a root canal. However, the bone can reattach to the root of the tooth once it’s put back into place.

It’s very important to get to the dentist as fast as possible, typically within one hour, to avoid the tooth being damaged any further.  There are several steps to take to assure safe and clean keeping.

Tips to follow to increase chances of saving the tooth:

  • Do not touch the root
  • If the tooth is dirty rinse it with milk. (Milk helps the roots survive) Water will do if you do not have milk.
  • Do not use fabric to clean the tooth
  • The most important thing is to keep the tooth moist.  Drop it in a glass of milk. If you can’t do this, place the tooth in your mouth, between the cheek and gum.
  • Try slipping the tooth back into its socket. If this does not happen easily revert back to the option above.

Teeth cannot always be saved, however.  At that point your dentist will discuss options of porcelain crowns and dental implants.

Once you are at the dentist he/she will rinse the tooth and asses the condition of the mouth and tooth. The dentist may perform a root canal right away, or may wait. It mostly depends on how long the tooth was out of the mouth.  The dentist will splint the avulsed tooth to the teeth on either side with a soft wire material. Usually splints the tooth to the surrounding teeth for 7 to 10 days. If the bone around the tooth also has been fractured, the tooth may have to be splinted for 6 to 10 weeks. Reimplanted teeth eventually need root canal treatment.  This will be used to hold the tooth in place for several days.  Your dentist will decide how long the splint should remain in.

Once the hard part is over your dentist will examine the tooth in three to six months. Unless there are signs of infection, the next visit will occur at your yearly checkup. The dentist will follow up for the next two to three years to ensure that the tooth re-implanted successfully.
