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 Bedford Orthodontics, Drs. Magda Barnard & Lee Erickson 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. Drs. Magda Barnard & Lee Erickson and our team at Bedford 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.

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Drs. Magda Barnard & Lee Erickson and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.

Xylitol is a naturally occurring sweetener found in tree bark, plants, fruits, and vegetables. The human body also produces it in small amounts. It looks and tastes like sugar, so as part of a health regimen, most people require no willpower to use it.

Xylitol is safe (approved by the World Health Organization) because only a small amount is needed for health benefits. With a glycemic index of seven, it is safe for diabetics. It has less than three calories per gram and 40% fewer calories than other carbohydrates. If eaten in extremely large amounts too quickly, it has a laxative effect in humans.

Tooth decay happens when bacteria in your mouth consume the sugars you eat. When you eat food that contains ordinary sugar, it gives energy to the bacteria on your teeth, allowing them to multiply and start making acids that destroy the enamel on the teeth.

Since xylitol is a natural sweetener derived from the fibrous parts of plants, it does not break down like sugar, so it helps maintain a neutral pH level in the mouth. Xylitol also prevents bacteria from sticking to the teeth because they are unable to digest it. That is how it protects the teeth from cavities.

With xylitol, the acid attack is diminished. With less bacteria and acid, your teeth stay healthier. The frequency of xylitol ingestion is important: aim for five grams a day, or one gram every three hours.

Studies of xylitol use as either a sugar substitute or a small dietary addition have demonstrated a dramatic reduction in new cavities. It has also stopped and even reversed some existing cavities. This effect is long lasting and possibly permanent. Low cavity rates persist even years after the trials have been completed.

Xylitol needs to be one of the first ingredients in a product to be effective. It is convenient and easy to use. You can find it in health food stores and specialty grocery stores. Xylitol can be delivered to your teeth in chewing gum, tablets, or even candy and mints.

It also comes in toothpaste, mouth rinse, baby oral wipes, gel and pacifiers, nasal wash, dry mouth spray, a granulated form for cooking, granulated packets to add to drinks, and commercially prepared foods. It can replace sugar on a one-to-one ratio.

Sweet rewards in xylitol are good for the body and the teeth! If you have specific questions please feel free to contact Bedford Orthodontics. We look forward to seeing you soon!

A famous mouthwash company chose the marketing slogan, “Better than flossing.” As a consumer, would you believe a high-end commercial that essentially tells you to stop flossing? Just use this brand of mouthwash and the risk of gingivitis, cavities, etc., is gone. What a wonderful idea! Now for the reality: This is simply not true.

The company that made these claims received some negative feedback for making this false claim. Does this mean that all mouthwashes are ineffective? Absolutely not. It takes a little bit of research to know which mouthwashes are most effective and best suited for you. Here are some key points to remember when choosing a mouthwash.

First, think about why you want to use a mouthwash. If you are at high risk for cavities, you would benefit from a fluoride mouthwash. Check the labels to see which ones contain fluoride.

If you have active gingivitis, a mouthwash with some antibacterial properties would be preferable. Read the labels carefully. You do not want a mouthwash containing alcohol. If you have active periodontal disease, an antibacterial mouthwash is appropriate, though you may want to discuss which kind would be best for your individual needs.

Prescription mouthwashes are also an option. You should pay close attention to the directions, such as how much and how long to use them. There is one brand in particular whose effectiveness can steadily diminish if you use it continually. There can also be side effects you should discuss with our office and/or your pharmacist.

Some great mouthwashes for kids change the color of plaque on their teeth to help them see how they are doing with their brushing. This is a great learning tool for the child and the parent! Why not pick up a bottle for yourself next time you’re at the store and evaluate your own performance?

Beware of claims that a mouthwash can loosen plaque. This is not accurate. Beware of any mouthwash that has alcohol. This is worth mentioning twice. Take care of your taste buds. If you are using a strong mouthwash, it can reduce your sense of taste.

These tips should help you choose the right mouthwash for your needs. Please contact Drs. Magda Barnard & Lee Erickson at our Bedford, NS office with any specific questions!
