Developing Teeth: Moving From Primary To Permanent



*Illustration created by InteliHealth designer Lynda Buchhalter
Because there are more permanent teeth than primary teeth, the permanent premolars come in behind the primary molars. Permanent molars emerge into an open space. The jaw lengthens as a child grows to create space for these permanent molars.
It takes about six years, between the ages of six and 12, for children to lose their primary (deciduous) teeth and gain their permanent teeth. This is called the period of "mixed dentition," because for much of the time, children will have both primary and permanent teeth. Teeth form under the gum before they erupt (emerge through the gum). The crown, or visible part of the tooth, forms before the roots do. Before the roots form, the developing tooth is called a "tooth bud."
Eventually, the 20 primary teeth are replaced by 32 permanent teeth. The primary molars are replaced by permanent premolars (also called bicuspids) and the permanent molars come in behind the primary teeth. Most often, the first teeth to emerge are the lower two front teeth (incisors) and the upper and lower first molars, the molars closest to the front of the mouth. They are followed by the upper two front teeth. The order that teeth emerge can vary. Parents should be more concerned about symmetry (the same teeth coming in at the same time on both sides) than the time teeth emerge.

Is It Your Jaw? Symptom Checklist for TMD

Temporomandibular disorders can cause symptoms that are similar to other diseases.

Do you notice clicking or popping when you open your mouth? Is it difficult or painful to open your mouth? Does your jaw occasionally lock, so it is stuck open or closed? If so, you should see your dentist for a consultation and examination. You may have a temporomandibular disorder (TMD). These disorders include problems of the chewing muscles, the jaw joint (called the temporomandibular joint or TMJ), or both.

Here are some key symptoms linked to TMD.

  • Unusual sounds — Clicking, grinding or popping sounds when you open your mouth are common in people with TMD. The sounds may or may not be accompanied by pain. According to the National Institute of Dental and Craniofacial Research, researchers believe that most people with popping or clicking in the jaw joint probably have a displaced disc. However, they also note that as long as the displaced disc causes no pain or problems with jaw movement, no treatment is needed.
  • Locking or limited movement — The jaw joint is similar to a ball-and-socket joint except that the socket itself is movable. The jaw joint sometimes may lock in an open or closed position. You may have difficulty opening your mouth either because the joint is locked or because of pain.
  • " Ear" pain — You may think you have an ear infection, but ear pain may be related to jaw joint inflammation or muscle tenderness. Pain from TMD is usually felt in front of or below the ear.
  • Headaches — People with TMD often report headaches. Your dentist can help to determine if your specific headache symptoms are a result of TMD. In some situations, you may need to consult a physician to help diagnose and treat certain headaches not related to TMD.
  • Morning stiffness or soreness — If your jaw muscles are stiff and sore when you wake up, it may by a sign that you are clenching or grinding your teeth in your sleep. Clenching or grinding teeth can exhaust jaw muscles and lead to pain.
  • Difficulty chewing — You may have difficulty chewing as a result of a change in your bite—the way your upper and lower teeth fit together. This shift in your bite may be related to TMD.
  • Previous injuries and related conditions — A recent injury to the jaw joint or one from many years past can lead to TMD symptoms. Arthritis in the joint also may arise from injury. Arthritis already affecting other joints may affect the jaw joint and lead to TMD.
  • Others — Though the research is controversial, a feeling of fullness of the ears or ringing in the ears may sometimes be related to TMD. In these cases, consultation with an "ear, nose and throat" physician can help establish the final diagnosis.
If these symptoms sound familiar, talk to your dentist. Your dentist will test your ability to open and close your jaw, examine other jaw movements, and feel the jaw joint and muscles for pain or tenderness. The dentist will listen with a stethoscope in front of the ear for any clicking, popping or grinding sounds and will feel the jaw joint while you open and close it.

X-rays are often taken to look at the jaw joint and to rule out other diseases. In some cases, a computed tomography (CT) scan may be needed to further examine the bony detail of the joint. In addition, magnetic resonance imaging (MRI) is sometimes recommended to analyze the soft tissues.

While it is advisable to discuss any TMD symptoms with your dentist, occasional discomfort in the jaw joint and chewing muscles is quite common and usually not a cause for concern. However, if you are diagnosed with TMD, the good news is that simple self-care practices are highly effective in relieving the discomfort. These include eating soft foods, applying heat or ice packs and avoiding extreme jaw movements. Effective, conservative treatments include nonsteroidal anti-inflammatory drugs, muscle relaxants, physical therapy and oral appliances.

Tooth Discoloration -- You Have Options


Your teeth can become discolored by stains on the surface or by changes in the tooth material. Dentists divide discoloration into three main categories:
  • Extrinsic discoloration — This occurs when the outer layer of the tooth (the enamel) is stained by coffee, wine, cola or other drinks or foods. Smoking also causes extrinsic stains.
  • Intrinsic discoloration — This is when the inner structure of the tooth (the dentin) darkens or gets a yellow tint. Causes include excessive exposure to fluoride during early childhood, the maternal use of tetracycline antibiotics during the second half of pregnancy and the use of tetracycline antibiotics in children 8 years old or younger.
  • Age-related discoloration — This is a combination of extrinsic and intrinsic factors. In addition to stains caused by foods or smoking, the dentin naturally yellows over time. The enamel that covers the teeth gets thinner with age, which allows the dentin to show through. Chips or other injuries to a tooth can also cause discoloration, especially when the pulp has been damaged.
In rare cases, children with a condition called dentinogenesis imperfecta are born with gray, amber or purple discolorations.

Symptoms

Symptoms include stains on the enamel or a yellow tint in the dentin.

Diagnosis

No special tests are needed. A dentist can diagnose tooth discoloration by looking at the teeth.

Expected Duration

Some tooth discoloration can be removed with professional cleaning, but many stains are permanent unless the teeth are treated (whitened) with a bleaching gel.

Prevention

Brushing your teeth after every meal will help to prevent some stains. Dentists recommend that you rinse your mouth with water after having wine, coffee or other drinks or foods that can stain your teeth. Regular cleanings by a dental hygienist also will help to prevent surface stains.
Intrinsic stains that are caused by damage to a nerve or blood vessel in the inner part (the pulp) of a tooth sometimes can be prevented by having root canal treatment, which removes organic material before it has a chance to decay and darken. However, teeth that undergo root canal treatment may darken anyway. To prevent intrinsic stains in children, avoid water that contains a high fluoride concentration. You can check the concentration of fluoride in your drinking water supply by calling the public health department. Then consult your dentist.

Treatment

Discoloration often can be removed by applying a bleaching agent to the enamel of the teeth. With a technique called "power bleaching," the dentist applies a light-activated bleaching gel that causes the teeth to get significantly whiter in about 30 to 45 minutes. Several follow-up treatments may be needed.
It's also possible to remove discoloration with an at-home bleaching gel and a mouth guard given to you by your dentist. The bleaching gels designed for use at home aren't as strong as those applied by your dentist, so the process takes longer — usually two to four weeks. Whitening toothpastes may remove minor stains, but they aren't very effective in most cases.
If you've had a root canal and the tooth has darkened, your dentist may apply a bleaching material to the inside of the tooth.
When a tooth has been chipped or badly damaged or when stains don't respond to bleaching, your dentist may recommend covering the discolored areas. This can be done with a composite bonding material that's color-matched to the surrounding tooth. Another option is to get veneers, which are thin shells of ceramic that cover the outer surfaces of the teeth.

When To Call a Professional

Tooth discoloration is mainly a cosmetic problem. Call a dentist if you're unhappy with the appearance of your teeth. Any change in a child's normal tooth color should be evaluated by a dentist.

Prognosis

The prognosis is very good for extrinsic stains. Intrinsic stains may be more difficult or take longer to remove.

Video: Gingivitis

From the ADA:

If your gums are tender, swollen or bleed easily when flossing, you may have gingivitis—the early stage of gum disease. Fortunately, gingivitis can be prevented by following a good oral health care routine and by regularly visiting a dentist. Find out more about how to reduce the risk of gingivitis and, if needed, how to treat it.
