Many people undergo orthodontic treatment during childhood, adolescence, and even into adulthood. Wearing orthodontic appliances like braces is sure to produce a beautiful smile. Though orthodontic treatments at Chan & Chen Orthodontics are designed to accommodate your lifestyle, chances are you will need to make some dietary modifications to prevent damage to your braces and prolong orthodontic treatment.
The First Few Days with Braces
The first few days wearing braces may be the most restrictive. During this time, the adhesive is still curing, which means you will need to consume only soft foods. This probably will not be a problem, however, as your teeth may be tender or sensitive while adjusting to the appliances.
Orthodontic Dietary Restrictions
You can eat most foods normally the way you did without braces. However, some foods can damage orthodontic appliances or cause them to come loose. Examples of foods you will need to avoid include:
- Chewy foods like taffy, chewing gum, beef jerky, and bagels
- Hard foods like peanuts, ice chips, and hard candy
- Crunchy foods like chips, apples, and carrots
How to Continue to Eat the Foods You Love Most
Keep in mind that you may still be able to enjoy some of the foods you love by making certain modifications to the way you eat them. For example, steaming or roasting carrots makes them softer and easier to consume with braces. Similarly, you can remove corn from the cob, or cut up produce like apples and pears to avoid biting into them. Other tips include grinding nuts into your yogurt or dipping hard cookies into milk to soften them. If you must eat hard candies, simply suck on them instead of biting into them.
If you have any question whether a food is safe to eat during your treatment with Chan & Chen Orthodontics, we encourage you to err on the side of caution. Of course, you can always contact our Andover office with any questions you have about your diet and the foods that should be avoided during treatment. By following our dietary instructions and protecting your orthodontic appliances from damage, you will be back to chewing gum in no time.

If you participate in sports or other physical activities, it’s wise to consider getting a mouthguard. Also known as mouth protectors, mouthguards are a device worn over the teeth to lessen the impact of a blow to the face.
This reduces the chance that you might lose teeth or sustain other serious oral injuries. We recommend that all patients involved in a contact sport such as wrestling, football, or hockey wear a mouthguard because of the high risk of such injuries.
However, anyone involved in a physically demanding sport or activity should wear a mouthguard as well.
Can you imagine what it would be like to lose a few of your front teeth? The way you talk, eat, and smile would all change. Potential injuries when you don’t wear a mouthguard include chipped and broken teeth, fractured jaws, root damage, damage to crowns and bridgework, concussions, and/or injury to the lips, cheeks, or gums.
Types of Mouthguards
There are three different types of mouthguards — typically made of a soft plastic material or laminate. You can decide which works best for you in terms of budget, fit, and comfort.
- Stock mouthguards are prefabricated to a standard size. They offer adequate protection, but you need to make sure you find one that fits properly and comfortably. Stock mouthguards are readily available at department stores, sporting goods stores, and online.
- Boil-and-bite mouthguards are placed in boiling water to soften them, then into the mouth so they can conform to the shape of the teeth. Boil-and-bite mouthguards are more expensive, but offer a more customized fit than stock ones. You can find these in department stores, pharmacies, sporting goods stores, and online.
- Custom-made mouthguards are created just for you by Dr. Kathleen Chan and Dr. Ivy Chen. These offer the best fit and comfort of all the options, but they are also the most expensive. Ask a member of our Andover team for more information.
The American Dental Association says a good mouthguard should be easy to clean, fit properly, be comfortable, and resist tearing or damage. It shouldn’t restrict speech or breathing.
Still not sure if you need a mouthguard or which kind is right for you? Ask Dr. Kathleen Chan and Dr. Ivy Chen or one of our staff members for more information.

According to the American Association of Orthodontists, orthodontic treatment for children should start at around age seven. Dr. Kathleen Chan and Dr. Ivy Chen can evaluate your child’s orthodontic needs early on to see if orthodontic treatment is recommended for your son or daughter.
Below, we answer common questions parents may have about the benefits of early childhood orthodontics.
What does early orthodontic treatment mean?
Early orthodontic treatment usually begins when a child is eight or nine years old. Typically known as Phase One, the goal here is to correct bite problems such as an underbite, as well as guide the jaw’s growth pattern. This phase also helps make room in the mouth for teeth to grow properly, with the aim of preventing teeth crowding and extractions later on.
Does your child need early orthodontic treatment?
The characteristics and behavior below can help determine whether your little one needs early treatment.
- Early loss of baby teeth (before age five)
- Late loss of baby teeth (after age five or six)
- The child’s teeth do not meet properly or at all
- The child is a mouth breather
- Front teeth are crowded (you won’t see this until the child is about seven or eight)
- Protruding teeth, typically in the front
- Biting or chewing difficulties
- A speech impediment
- The jaw shifts when the child opens or closes the mouth
- The child is older than five years and still sucks a thumb
What are the benefits of seeking orthodontic treatment early?
Jaw bones do not harden until children reach their late teens. Because children’s bones are still pliable, corrective procedures such as braces are easier and often faster than they would be for adults.
Early treatment at our Andover office can enable your child to avoid lengthy procedures, extraction, and surgery in adulthood. Talk with Dr. Kathleen Chan and Dr. Ivy Chen today to see if your child should receive early orthodontic treatment.

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 Chan & Chen Orthodontics, Dr. Kathleen Chan and Dr. Ivy Chen 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. Kathleen Chan and Dr. Ivy Chen and our team at Chan & Chen Orthodontics 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 Andover office and we will be happy to answer any of your questions!
