It might be the most wonderful time of the year, but if you’re dashing through the snow to an emergency orthodontic appointment, you’re not feeling very jolly. And post-holiday, no one wants to start off their New Year’s Resolutions with “Get Cavities Filled.” How to survive the sweetest of seasons with braces and enamel intact?

Candies and sweets would normally be on the naughty list, but we’re not Scrooges! Indulging in a treat or two is part of the holiday fun, and we have some advice for how to enjoy them guilt-free. But first, some treats are definitely more naughty than nice. Which are the ones that are better as decorations than desserts?

• Candy Canes

If you’ve ever suffered a broken bracket or a chipped tooth after an innocently biting down on a much-harder-than-expected piece of candy, you know that caution is in order. That’s why we tend to savor candy canes, letting them dissolve slowly in the mouth. Of course, the drawback to this strategy is that now we’re slowly bathing our teeth in sugar, encouraging the growth of plaque and cavity-causing bacteria.

Candy canes, peppermints, and other hard candies are potentially bad for your teeth and braces when you crunch away, and definitely bad for your teeth if you let them dissolve slowly.

• Gumdrops

Glistening, colorful gumdrops. Roofing your gingerbread house, trimming a gumdrop tree, or simply sitting in a bowl, they are one of the sweetest ways to decorate for the holidays.  And when we say “sweet,” we mean that literally. Most gumdrops are basically made of corn syrup and sugar—and then rolled in more sugar.

But their sugar content isn’t the only problem. This is sugar in an extra-gummy form that sticks between our teeth and along our gums, and gets caught around brackets and wires.

• Toffees, Caramels, Taffy

They might come in lovely ribboned boxes, but these extremely sticky foods are not a gift to your teeth.

Not only do chewy candies stick to enamel, they stick to fillings, crowns (especially temporary crowns), and orthodontic wires and brackets. No one wants an unexpected trip to the dentist or orthodontist because dental work has been damaged or dislodged!

• Gingerbread Houses

Nothing says the holidays like a gingerbread house—chewy, sticky gingerbread covered with hard sugar icing, gumdrops, and peppermints. Great for your décor; not so great for your dental health. Eat one gingerbread man if you’re in a spicy mood and leave your architectural masterpiece intact.

Well, this list wasn’t very jolly. So as a little holiday gift for you, here are some suggestions to help you enjoy your desserts in the healthiest way possible.

• Be choosy.

Just like you search for the perfect presents for your family and friends, take the time to choose the perfect holiday treats for yourself. If you are wear braces, or are worried about cavities, or are just generally concerned with your oral health, stay away from sticky, hard, and excessively sugary desserts.

What can you accept from your holiday hosts with a grateful (and relieved) smile? The occasional soft chocolate should be nothing to stress about—and if you make it dark chocolate, you’ll actually get nutritional bonuses like magnesium and antioxidants. Soft cakes, cupcakes, cookies, and pies should be braces-friendly—yes, they are made with lots of sugar, but it is the holidays after all. Just be sure to follow our next suggestions to make that slice of cheesecake guilt-free.

• Eat sweets with a meal.

Saliva does more than keep our mouths from getting dry. It also helps prevent cavities by washing away food particles and neutralizing the acids from food and bacteria which damage enamel.

Eat dessert with a meal, and you benefit from increased mealtime saliva production. When you snack throughout the day, this acid-neutralizing ability is greatly reduced.

• Rinse after eating.

Rinsing your mouth with water after a meal or a snack, especially a sugary one, also helps wash away the sugars and carbs which oral bacteria convert into cavity-causing acids.

• Brush immediately. (Maybe.)

If you wear braces, you want to make sure there are no food particles stuck around your brackets and wires. If you wear aligners, you want to get rid of food particles on and around your teeth before you replace your aligners after eating.

But if you’ve eaten acidic foods like citrus or colas, the acids in the food can weaken your enamel just enough to cause some potential enamel damage if you scour your teeth immediately after eating. We often recommend waiting about 30 minutes to brush to give your enamel a chance to recover.

Since every mouth is different, especially when you wear braces, talk to Dr. Susan So for the best times and methods for holiday brushing.

You don’t want to ho-ho-hope that we can fit you in at our Castro Valley, CA office for a bracket repair. Make your holiday dessert list and check it twice, and make sure you’re brushing and flossing more often if you’re indulging in seasonal treats—give yourself these two gifts, and you’ll be ringing in the New Year with a beautiful, healthy smile. Sweet!

There are so many adults and teens in our Castro Valley, CA office who would love to have their teeth straightened but that are unwilling to go through the long and unsightly process of traditional metal braces. Well, that's where Invisalign® and Invisalign Teen® come to the rescue; the most advanced clear aligner systems in the world!

There are several reasons why, if you're considering getting braces, you should consider Invisalign too. Here are some of them:

• You can eat whatever food you'd like, without worrying about it getting caught in wires or breaking brackets.
• Most people won't even know you're wearing them!
• If you need to, you can remove your aligners at any time.
• The removable aligners let you brush and floss as you normally would, making for better overall oral health.
• Since they are made of a smooth BPA-free plastic, Invisalign aligners are simply more comfortable to wear than traditional braces. No metal means no more roughed up gums or irritated tongue!
• You'll need to visit our Castro Valley, CA office less often — only once every six weeks or so.
• With Invisalign Teen, you’ll receive up to six replacements for lost or broken aligners.

Before you get started with treatment, you’ll have a consultation with Dr. Susan So to see if Invisalign or Invisalign Teen is right for you. If your case is a good fit, then you’ll have X-rays, pictures, and impressions of your teeth taken. That information will be used to make the 3D models of your teeth that let Dr. Susan So see how they will move throughout the entire treatment and approximately how long it will take.

After that, you’ll receive your aligners based on the treatment plan we recommend. You’ll get a new set of aligners every two weeks. Then all you need to do is wear your aligners 22 hours a day and you’ll be on your way to a straighter healthier smile. Don’t hesitate to a member of our Castro Valley, CA team for more information about Invisalign!

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 Castro Valley Orthodontics, Dr. Susan So 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. Susan So and our team at Castro Valley 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 Castro Valley, CA office and we will be happy to answer any of your questions!

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. Susan So. These offer the best fit and comfort of all the options, but they are also the most expensive. Ask a member of our Castro Valley, CA 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. Susan So or one of our staff members for more information.
