Dental Braces

Dental Braces by San Diego Smile Center Mira Mesa


Dental braces are wire-based appliances that orthodontists use to correct crowded and misaligned teeth or jaws. Many people who need dental braces get them during their early teenage years, but adults also can benefit from wearing braces. The goal of dental braces is to properly align your teeth and jaws to produce an even bite and pleasing smile.

For minor corrections, an option is a series of customized, removable appliances called clear aligners or "invisible braces." These may have a more acceptable appearance to some adults. If you're considering clear aligners versus fixed braces, ask about the cost and the pros and cons for your specific needs. Many people need fixed braces to properly correct their dental problems.

Modern materials and technologies make the experience of having dental braces much more comfortable than in the past.


Why it's done

Dental braces offer corrective treatment for:

  • Overcrowded or crooked teeth

  • Too much space between teeth

  • Upper front teeth that overlap the lower teeth too much — either vertically (overbite) or horizontally (overjet)

  • Upper front teeth that bite behind the lower ones (underbite)

  • Other jaw misalignment problems that cause an uneven bite

Proper alignment of your teeth and jaws may improve not only the appearance of your teeth but also the health of your mouth and the way you bite, chew and speak.

Adults and braces

If you're an adult with braces, you may need to wear them longer than a younger person would, but they can still produce similar results — for example, correcting crooked teeth or a misaligned jaw. Because your facial bones are no longer growing, however, there may be some problems that can't be corrected with braces alone.

How Do Braces Work?

In their entirety, braces work by applying continuous pressure over a period of time to slowly move teeth in a specific direction. As the teeth move, the bone changes shape as pressure is applied.

Braces are made up of the following components:

  • Brackets are the small squares that are bonded directly to the front of each tooth with a special dental bonding agent or are attached to orthodontic bands. Brackets act like handles, holding the arch wires that move the teeth. There are several types of brackets, including stainless steel and tooth-colored ceramic or plastic, which are often selected because they’re less obvious. Occasionally, brackets are cemented to the back of teeth, in order to hide them from view.

  • Orthodontic bands are stainless steel, clear, or tooth-colored materials that are cemented to the teeth with dental bonding agents. They wrap around each tooth to provide an anchor for the brackets. The clear or tooth-colored bands are more cosmetically appealing options but are more expensive than stainless steel. They are not used in all patients. Some people have only brackets and no bands.

  • Spacers are separators that fit between teeth to create a small space prior to placement of orthodontic bands.

  • Arch wires attach to the brackets and act as tracks to guide the movement of the teeth. Arch wires can be made of metal or be clear or tooth-colored.

  • Ties are small rubber rings or fine wires that fasten the arch wire to the brackets. They can be clear, metal, or colored.

  • A buccal tube on the band of the last tooth holds the end of the arch wire securely in place.

  • Tiny elastic rubber bands, called ligatures, hold the arch wires to the brackets.

  • Springs may be placed on the arch wires between brackets to push, pull, open, or close the spaces between teeth.

  • Two bands on the upper teeth may have headgear tubes on them to hold the facebow of the headgear in place. (A headgear is another tool used by orthodontists to aid in correcting irregularities of the teeth; see below)

  • Elastics or rubber bands attach to hooks on brackets and are worn between the upper and lower teeth in various ways. They apply pressure to move the upper teeth against the lower teeth to achieve a perfect fit of individual teeth.

  • Facebow headgear is the wire gadget that is used to move the upper molars back in the mouth to correct bite discrepancies and also to create room for crowded teeth. The facebow consists of an inner metal part shaped like a horseshoe that goes in the mouth, attaching to buccal tubes, and an outer part that goes around the outside of the face and is connected to a headgear strap.

Newer “mini-braces,” which are much smaller than traditional braces, may be an option for some. There is another method of straightening teeth that uses removable plastic retainers that may also work when crowding of the teeth is not too severe. Your orthodontist will discuss the various types of braces with you and determine which might be the best option for your situation.
