Malocclusions (bad bites) may cause more than an appearance problem — with teeth and jaws not working together properly, you’re at higher risk for dental disease or accelerated tooth wear. Fortunately, most malocclusions can be corrected through orthodontics, a specialty for moving teeth to better functioning and more attractive positions.
If you’re considering orthodontic treatment for a malocclusion, here are the basics on 3 of the most common orthodontic appliances used for straightening misaligned teeth.
Metal Braces. These appliances have a proven track record for correcting most forms of malocclusion. Braces consist of metal brackets bonded to the front teeth and an anchor band to the back teeth. A thin metal wire passes through the brackets to attach to the bands in the back. Gradually increased tension in the wire incrementally moves the teeth to the desired position.
Clear Bracket Braces. While metal braces do an effective job of tooth movement, they leave less to be desired in appearance. Made of polymer material rather than metal, clear bracket braces offer a more appealing look. But while they’re similar in construction to the metal version, they’re more susceptible to breakage. Wearers must be extra cautious and avoid hard foods or extreme physical sports contact.
Clear Aligners. The previous appliances are fixed and can’t be removed by the wearer. Clear aligners take a different approach with removable plastic trays that fit snugly over the dental arch. A series of trays are computer generated to carefully match the patient’s mouth structure, each incrementally smaller than the previous one in the series. After wearing the first tray for two or three weeks, the wearer changes to the next (and slightly smaller) tray in the series, repeating the process until all the trays have been worn. Of the three options, the clear aligners offer the best appearance; however, they’re best suited for cases that don’t require complex movements.
We can advise you which option is best for you after a complete evaluation, factoring in age, lifestyle and the complexity of your malocclusion. Regardless of the choice, the aim is the same — achieving a healthier mouth, better function and a more attractive smile.

Many things can affect your child’s future dental health: oral hygiene, diet, or habits like thumb sucking or teeth grinding. But there’s one you might not have considered: how they breathe.
Specifically, we mean whether they breathe primarily through their mouth rather than through their nose. The latter could have an adverse impact on both oral and general health. If you’ve noticed your child snoring, their mouth falling open while awake and at rest, fatigue or irritability you should seek definite diagnosis and treatment.
Chronic mouth breathing can cause dry mouth, which in turn increases the risk of dental disease. It deprives the body of air filtration (which occurs with nose breathing) that reduces possible allergens. There’s also a reduction in nitric oxide production, stimulated by nose breathing, which benefits overall health.
Mouth breathing could also hurt your child’s jaw structure development. When breathing through the nose, a child’s tongue rests on the palate (roof of the mouth). This allows it to become a mold for the palate and upper jaw to form around. Conversely with mouth breathers the tongue rests behind the bottom teeth, which deprives the developing upper jaw of its tongue mold.
The general reason why a person breathes through the mouth is because breathing through the nose is uncomfortable or difficult. This difficulty, though, could arise for a number of reasons: allergy problems, for example, or enlarged tonsils or adenoids pressing against the nasal cavity and interfering with breathing. Abnormal tissue growth could also obstruct the tongue or lip during breathing.
Treatment for mouth breathing will depend on its particular cause. For example, problems with tonsils and adenoids and sinuses are often treated by an Ear, Nose and Throat (ENT) specialist. Cases where the mandible (upper jaw and palate) has developed too narrowly due to mouth breathing may require an orthodontist to apply a palatal expander, which gradually widens the jaw. The latter treatment could also influence the airway size, further making it easier to breathe through the nose.
The best time for many of these treatments is early in a child’s growth development. So to avoid long-term issues with facial structure and overall dental health, you should see your dentist as soon as possible if you suspect mouth breathing.
For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
