Common Malocclusions

December 24th, 2025

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. Cronin and our team recommend an orthodontic assessment at our Langley 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. Cronin 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. Cronin will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.

Foods that are Safe for Braces

December 17th, 2025

Orthodontic braces are used to straighten the teeth, which not only creates a more pleasing appearance, but also helps prevent tooth decay and other oral health problems. Braces are only effective when they are properly cared for, however. Certain foods, for example, are better suited for individuals who have braces, as opposed to hard and sticky foods that can cause damage. So, what types of foods should you or your kids eat to protect dental appliances?

The best foods to eat with braces are those that are not high in sugar and do not require excessive chewing. For breakfast, try eggs, yogurt, bacon, wheat toast, or oatmeal. Lunch may steer toward a banana rather than an apple, a salad without nuts, and a glass of water. If you are looking for some after-school snacks for your kids, consider baked tortilla chips with salsa and guacamole, or try string cheese with fruit.

A healthy dinner can include most types of vegetables, so long as they are cooked to an appropriate softness. Pair that with a lean protein, such as fish or chicken, and follow up with dessert. Just be sure to brush afterward!

Post-Tightening Foods

As braces begin to adjust the alignment of the teeth, our team at Cronin Ortho will periodically tighten them to continue the alignment process. After tightening occurs, the teeth may be sore and sensitive to certain foods. During this time, it is best to eat soft foods. Examples include:

  • Pudding
  • Mashed potatoes
  • Soup
  • Ice cream
  • Cottage cheese
  • Peas
  • Pancakes
  • Pasta

Foods to Avoid

Anyone who wears braces – whether fixed or removable – should avoid excessive snacking and should aim to eat a healthy and balanced diet. It is also important to avoid foods that could cause damage to the braces, such as:

  • Hard candies
  • Gum
  • Nuts
  • Popcorn
  • Certain raw vegetables (for example, carrots)

Considerations

Regardless of what types of foods you eat with braces, it is important to keep the crevices between the teeth and around the braces very clean. That means brushing and flossing after meals to prevent the build-up of plaque and decay. Not only can failing to do so damage the teeth, but it can also cause discoloration.

Permanent or Removable Retainers: Which is right for you?

December 10th, 2025

When the time comes for Dr. Cronin to remove your braces, it is very exciting. Unfortunately, it can be somewhat confusing, too, because you are faced with choosing between two kinds of retainers. Should you go with permanent, removable, or a combination of the two? It is always wise to follow Cronin Ortho recommendations, but knowing more about the two types of retainer beforehand can be helpful.

Removable Retainers

Removable retainers offer the advantage of easy use: you will generally put a removable retainer in at night and take it out in the morning. Regardless of your retainer schedule, you'll be able to enjoy some time with no retainer. However, a removable retainer can easily be forgotten at times, and this means you won't be taking full advantage of teeth retention.

Another potential advantage of a removable retainer is that you can take it out and brush and floss your teeth with ease, which is more of a challenge with a permanent retainer. Although removable retainers can be very effective, they don't tend to be as effective as permanent retainers, especially if they are not used as directed.

Permanent Retainers

Permanent retainers are the clear choice for patients who want to “get it and forget it.” Once your permanent retainer is placed in your mouth, you won’t need to worry about daily retainer schedules, since it is permanently affixed to your teeth.

Because teeth begin to shift naturally as we age, a permanent retainer typically offers better long-term results for teeth straightening than a removable one. You can't forget to put it in — it's already there! Temporary retainers get lost or are forgotten on trips, and often fail to get used as often as they should be.

One drawback to permanent retainers is flossing. Some patients find it more difficult to floss with a permanent retainer, but we can show you effective ways to floss fairly quickly with your permanent retainer.

Some orthodontists may recommend a combination of the two; for example, a removable retainer for the top teeth and a permanent one for the lower ones because the lower teeth are smaller and tend to shift more.

Ultimately, the most important thing to remember is that wearing your retainer as directed is extremely important. As long as you follow our orthodontist’s advice, you will get the best results from your retainer, regardless of its type.

Holiday Gift Ideas for Healthy Holiday Smiles

December 3rd, 2025

Need some gift ideas for family members and friends who seem to have absolutely everything? Who are impossible to shop for? Who tell you not to worry, it’s the thought that counts? Well, we have a few suggestions to show your loved ones that you’ve put a lot of thought into their gifts this holiday season. 

You love to see your friends and family smile, so we’ve come up with some smile-worthy ideas curated to their specific interests. And they’re braces-friendly, too!

Environmental Ally

The world is becoming a more eco-conscious place, and happily this transformation includes products designed for personal care. Put together a spa basket which is good for your friend’s dental health and the planet!

A recyclable gift box containing zero-waste, environmentally friendly bath products and organic cotton face cloths becomes even more mindful with the addition of bamboo or recycled plastic toothbrushes, bamboo interdental picks, and biodegradable floss. 

Don’t forget to include a colorful, insulated water bottle for sustainable hydration—and washing away food particles when there’s no handy place to brush after eating. Healthy planet/healthy smile.

Talented Techie

If your friend or relative is high-tech all the way, maybe it’s time for a dental upgrade. 

Water flossers are a great way to eliminate stubborn plaque around brackets and behind wires. Adjustable water pressure applies just the right amount of cleaning power. The flow can be directed to the gumline, between teeth, around brackets, or anywhere else needed. Some models even offer tapered heads with brushes designed specifically for cleaning braces. 

And for an extra thoughtful touch, include a packet of plaque disclosing tablets. Chewing one of these helpful little tablets will reveal any plaque that’s still on the teeth.

Adventure Seeker

How about a new backpack or carry-all for outdoor or travel adventures? A travel first aid kit is always a welcome addition for the person on the go.

Go the extra step and help a friend be prepared for anything with an emergency dental kit designed for braces. You can find these lightweight kits in stores or online, or you can assemble one yourself with a travel-size orthodontic toothbrush and toothpaste, floss threaders and floss, interproximal brushes, a travel mirror, and, of course, orthodontic wax in a handy kit bag. Include a pack of sugar-free gum—it helps with altitude changes and hydration. Ask Dr. Cronin or the team at Cronin Ortho for suggestions!

Film Buff

If your bestie likes nothing better than an evening spent in front of the home screen, consider a subscription or gift card for a streaming service tailored to his or her favorites, whether it’s classic films, sci-fi, action, rom-coms, or epic adventures. 

And don’t forget the binge-watch treats! Fill a basket with braces-friendly goodies like peanut butter cups, junior mints, soft chocolate truffles, and some sparkling water. Maybe add a gift card for healthy smoothies and ice cream. Who needs popcorn and sodas?

No matter who’s on your shopping list, tailoring your gifts to their interests and their well-being is a great way to share happy, healthy holiday smiles with family and friends in Langley.
