Common Malocclusions

July 6th, 2022

When we think orthodontics, we commonly think teeth. Naturally! Straight teeth and a beaming smile are everyone’s orthodontic goal. But orthodontics is a field which specializes in more than misaligned teeth. While your beautifully aligned teeth are the visible outcome of your orthodontic work, a properly aligned bite is the foundation for your healthy smile.

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when the mouth is closed. A malocclusion, or bad bite, affects many people to some degree, but not always in exactly the same way. Some of the different types of malocclusion include:

  • Crossbite

A crossbite occurs when upper teeth fit inside lower teeth. An anterior crossbite refers to the front teeth, with one or more upper front teeth, or incisors, fitting behind lower front teeth. A posterior crossbite affects the back teeth, with upper teeth fitting inside the lower teeth on one or both sides of the jaw.

  • Crowding

When the jaw is small and/or the teeth are large, lack of space can result in crowded, twisted, or crooked teeth.

  • Open bite

An anterior open bite means that the front teeth don’t close when biting down, leaving an open space between the upper and lower teeth. A posterior open bite occurs when the back teeth don’t make contact when the front teeth close.

  • Overbite

Our upper front teeth naturally overlap the lower ones a small bit when the teeth are closed. An overbite occurs when the upper teeth significantly overlap the lower teeth.

  • Overjet

When the upper front teeth protrude too far forward over the bottom teeth, it’s called an overjet, or, sometimes, buck teeth. Where an overbite causes a vertical overlap, an overjet takes into account the horizontal relationship of the teeth.

  • Spacing

A jaw that is large, teeth that are small, missing teeth—these conditions can lead to gaps between the teeth.

  • Underbite

An underbite results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

If you have a malocclusion, what comes next? This depends.

Some malocclusions are so minor that no treatment is necessary. Some are the result of misaligned teeth. Some occur because the upper and lower jaws are growing at different rates. Some are a combination of teeth and jaw misalignments. Some are caused by genetics, while others are caused by injuries or habits like prolonged thumb sucking or tongue thrusting.

Because malocclusions are so varied, your treatment plan will be designed for your specific needs. Braces, aligners, appliances like the Herbst® appliance or the palatal expander, surgery for severe malocclusions—there is a larger variety of treatment options than ever before to help you achieve a healthy bite.

When teeth and jaws don’t fit together as they should, the consequences can be damaged teeth and enamel, problems with the temporomandibular joint, headaches and facial pain, and difficulty chewing, eating, and speaking.

The good news is that early intervention for children can help correct teeth and jaw problems before they become more serious, leading to easier orthodontic care in the teen years, and helping to avoid the possibility of surgery or extractions. This is why Dr. Daniel Ma and our team recommend an orthodontic assessment at our Vancouver, BC office for children around the age of seven.

If you’re an adult with concerns about your teeth or bite, there’s good news for you, too. Dr. Daniel Ma can devise a treatment plan to improve your bite and your smile no matter what your age.

Of course, despite our title, there’s really no such thing as a “common malocclusion” when we’re talking about your dental health. Each person—and each smile—is unique. Dr. Daniel Ma will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.

TMD Problems and How You Can Prevent Them

June 29th, 2022

Temporomandibular joint disorders (TMD) describe a set of conditions that involve trouble with your jaw and face muscles. They result from a problem in the temporomandibular joint (TMJ), which is a hinge that connects the temporal bones, in your skull in front of each ear, to your jaw. The joint enables you to talk, yawn, and chew by letting your mouth move.

TMD can be very painful and interfere with functions such as eating and speaking. This what to watch for and how to try to prevent TMD.

Risk Factors for TMD

You are at higher risk for TMD if you are a women than if you are male. The disorder is most common among adults between the ages of 20 and 40 years. Other risk factors for TMJ disorders include the following.

  • Arthritis in the area, making movement more difficult
  • Excessive tooth grinding, because it increases stress on the joint
  • General stress, which can lead you to clench your teeth and strain facial muscles

Symptoms of TMD

Symptoms of TMD can last for just a short while, or for several years. Seeing Dr. Daniel Ma is important if your symptoms make it impossible for you to eat regularly or if you have unbearable pain or discomfort. The following symptoms can occur on both or one side of your face.

  • Aching or very tired facial muscles
  • Jaws that are fixed open or shut without you being able to unlock them
  • Grating or popping sounds when you chew or close or open your mouth
  • Pain in the entire area, including the mouth, jaw, neck, or shoulders, that comes on when you chew or yawn

Preventing TMD

You can try to prevent TMD by focusing on reducing risk factors. If you grind your teeth at night, ask Dr. Daniel Ma about wearing a mouthguard. If you are overly stressed, look into ways to better manage your stress and relax your muscles. Another strategy for trying to prevent the development of TMD is to avoid chewing gum, since that puts stress on your jaw.

If you have questions about TMD, don’t hesitate to contact our Vancouver, BC office.

The Importance of Wearing Your Retainer after Orthodontic Treatment

June 22nd, 2022

It's the big day and your braces are finally coming off! Does that mean you are completely done? Not so fast! After you complete your treatment here at our office, Dr. Daniel Ma and our team will recommend you wear a retainer, which must be worn routinely after treatment in order to hold your teeth in their proper, new position while your gums, ligaments and bones adapt. Most patients are required to wear their retainer every night at first, with many also being directed to wear them during the day. It's important to know there are different kinds of retainers, and today we thought we would explain the differences between them.

Hawley Retainers

The Hawley retainer is one of the most common types of retainers. It is a removable retainer made of a combination of a metal wire that typically surrounds the six anterior teeth and is designed to keep your teeth in place. This retainer is made from impressions of your teeth so that it fits snugly and comfortably in the roof of your mouth, while the wire and acrylic framing keeps your teeth in an ideal position. The acrylic can also be personalized with a large number of colors or patterns.

Essix (Clear) Retainers

The Essix retainer is a transparent removable retainer that fits over the entire arch of your teeth. This clear or transparent retainer fits over the entire arch of teeth and is produced from a mold. Similar to Invisalign’s clear aligner trays, Essix retainers have no metal or wires. They can also be used to produce minor tooth movements and can be helpful in prevention of tooth wear due to tooth grinding at night.

Bonded Retainers

Bonded lingual retainers are cemented directly to the inside surface of your lower canines. Dr. Daniel Ma and our team at our office encourage our patients with bonded lingual retainers to be careful with their bite as the bonding material may break due to incorrect biting and cause your teeth to shift. As with removable retainers, it is important to keep your bonded retainers clean. When brushing, make sure to carefully clean the inside of your lower teeth, as well as the wire itself.

The retention phase of treatment begins when the patient’s braces are removed. Retainers are worn full time, typically for the first nine months, except while eating. Retainers should also be removed before brushing your teeth.

If you have any questions about the retainers we offer or to learn more about post-orthodontic treatment, please feel free to contact us at our convenient Vancouver, BC office and we will be happy to answer any of your questions!
