What Is Cementum?

What Is Cementum?

Cementum is a hard layer of tissue that helps the periodontal ligament attach firmly to a tooth. Made of cementoblasts, cementum slowly forms over a lifetime.

Cementum is a hard, calcified layer of tissue that covers the root of the tooth. On its outer side, cementum is attached to the periodontal ligament; on its inner side, the dentin. Along with the periodontal ligament, alveolar bone and gingiva, cementum helps a tooth stay in its place. In fact, if it weren’t for cementum, the periodontal ligament wouldn’t be able to attach firmly to a tooth.

Slowly formed throughout life, cementum is created when the root of the tooth excretes cementoblasts. Though cementoblasts are somewhat of a mystery, it is known that cementum is yellow in color and softer than dentin. Its chemical makeup is similar to that of bone — but unlike bone, cementum is avascular (not supported by blood vessels).

Types of Cementum

There are three types of cementum: acellular cementum, cellular cementum and afibrillar cementum. Acellular cementum covers about 1/3-1/2 of the root and has little to no cellular components. Cellular cementum covers about 1/3-1/2 of the apex and is permeable. Afibrillar cementum sometimes extends onto the enamel of the tooth.

If you have periodontal disease, your acellular cementum, cellular cementum or afibrillar cementum may also be diseased. A gum disease treatment called scaling and root planing can be performed to remove the diseased cementum, as well as dental tartar and diseased dentin.

Why So Sensitive? 5 Reasons Why Your Teeth Hurt

Do your teeth hurt when you drink or eat something hot or cold? Most people think this is normal, but that’s not always the case. When your teeth hurt, they’re trying to tell you something: See your dentist.

More often than not, tooth sensitivity is a sign of a dental problem like tooth decay or gum disease. But there are other reasons why your teeth may be hurting:

  • You might have a cracked or broken tooth
  • One of your fillings could be broken or rotten
  • You might be grinding your teeth while you sleep
  • You could be brushing your teeth too hard
  • There might be dental plaque buildup on your tooth roots

Don’t make the mistake of ignoring sensitive teeth or trying to self-treat. If your sensitivity lasts longer than a couple of days or keeps recurring over a couple of weeks, make an appointment to see your dentist. The longer you wait, the worse it can get and the more expensive treatment will be. A quick exam can reveal exactly what’s going on and get you back to living pain-free.

Keep Waking Up With Headaches?

 

If the first thing you feel in the morning is a headache or pain behind your eyes or pain in your neck and shoulders, come in for a visit. What you’re experiencing could be the result of problems in your mouth. These are common symptoms of a condition known as temporomandibular joint disorder (TMJ), which basically means that your jaws don’t align properly. This misalignment stresses the jaw joints, putting pressure on nerves and muscles – which can result in morning headaches, migraines or facial and neck pain.
Not everyone with TMJ disorder shows symptoms. And not everyone has headaches or pain; TMJ disorder can also lead to broken teeth or fillings, loose teeth and toothaches. What is certain is that if you do display any of these symptoms, they won’t get better without professional help.
Many people find that resting the jaw helps ease the pain. You can do this by eating soft foods, avoiding chewing gum and hard candies. We can also show you jaw exercises to stretch the jaw joints and relieve stress. For most people, the most effective treatment is a custom dental splint that fits over your upper and lower teeth. This reduces the damage done from repeated clenching of the jaw or teeth grinding.
If these conservative methods don’t work, you still have other options. The temporomandibular joints can be flushed out, or an injection of cortisone can help relieve inflammation and pain. Worse-case scenario, you might need surgery. Come in for a visit and we’ll help you find the right solution.

Extra Cavity Protection for Kids

You might think that cavities are inevitable for kids, but in truth, they’re not. A healthy diet mixed with good oral hygiene (brushing and flossing) plus regular dental visits can prevent tooth decay. Dental sealants can reduce the risk even more. In fact, studies show that dental sealants can reduce decay in school children by 70%.
Dental sealants are thin plastic coatings that are applied to the grooves of back teeth, where tooth decay is usually a problem for kids and teens. Sealants act as a barrier between the chewing surfaces by blocking pieces of food and germs.
Sealants work best on permanent molars, which usually erupt at age 12. It’s best to have sealants applied soon after the permanent molars erupt so that decay doesn’t have a chance to develop.
Because they’re so thin, dental sealants won’t have an effect on your child’s speech or make chewing difficult. Sealants can be clear or slightly tinted; either way, they’re virtually invisible to the naked eye.
Though they don’t take much time to apply, sealants can last 5-10 years. Dental sealants are some of the most comfortable, cost- and tooth-saving solutions around!
