Three Reasons We're Fans of Fluoride

March 29th, 2023

Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

  1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions that are found in our saliva to restore any minerals that have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals. Even better? These new crystals are more resistant to acids.

  1. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride was important when you were younger and still had your baby teeth. This is because fluoride joined with minerals in your adult teeth while they were growing and developing, creating stronger, more cavity-resistant teeth even before they erupted.

And now that your permanent teeth are here, you’re still in luck! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, remineralizing and strengthening the tooth surface and helping repair weak spots in your enamel.

  1. It’s Easy to Get Fluoride Protection

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride in our diet each day. If your community’s water is low in fluoride, Drs.Rashed and Raziee can help you. Prescription fluoride rinses, gels, supplements, and other treatments are available at our Richmond Hill, ON orthodontic office to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them.

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral every time you brush. Keeping up with your brushing is especially important while you’re in orthodontic treatment.

Because wearing traditional braces can mean it’s harder to reach all the plaque on your teeth, especially behind wires and around your brackets, that demineralization we talked about earlier is a common problem during treatment. Demineralization often leads to discolored white spots on enamel and, eventually, cavities. If you need more protection than toothpaste alone provides, Drs.Rashed and Raziee will suggest fluoride treatments to reduce the risk of demineralization and even reverse some of its effects.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. And sealants for both kids and adults provide long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter that’s simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

What are dental sealants and how do they work?

March 29th, 2023

A dental sealant is a liquid that is applied to the teeth. The sealant hardens and provides a protective coating that is designed to reduce cavities and create a smoother tooth surface. Dental sealants are clear or white; they do not take away from the appearance of teeth. You can think about this treatment as being similar to varnish that protects a wood floor.

Sealants are not the same as fluoride treatments. The application is similar, but sealants are a semi-permanent protective coating. Drs.Rashed and Raziee and our staff recommend that sealant applications for children begin soon after molars erupt, first molars around the age of six, and second molars around the age of 12.

Simple Application

Having sealants applied is not uncomfortable at all. First, your child's teeth will be cleaned and dried. A gel is applied, which helps the sealant adhere to the tooth, and then is rinsed away. Your child's teeth are dried again and the sealant is applied. A few seconds of exposure to a light source may be used to cure the sealant and make it semi-permanent. Sealants should last for a long time, normally between five and ten years.

Sealant Benefits

The coating on the surface of your child's teeth reduces the amount of acid contact. Normal acids in foods that are consumed can eat away at the surface of teeth. Bacteria also react to plaque formation and create more acid in the mouth. These small pits or weakened areas are prone to caries or cavity formation. Preventing cavities is a much better choice than drilling and filling damaged teeth.

A sealant also helps to smooth the chewing surfaces of your childn't teeth. The smoother surface is not as likely to retain small particles of food and bacteria. Your child's mouth stays cleaner and food is not left behind to form acids. The protective application can also be used on other teeth that have a rough surface, to protect the grooves or pits from decay.

After the sealant is applied, your child still needs to take proper care of his or her teeth. Regular brushing and flossing is required. Drs.Rashed and Raziee may recommend fluoride treatments to strengthen and protect your child's teeth further.

If you have any concerns about sealants, please discuss them with during your child's next appointment at Smiles on Yonge. We want your little one's teeth to stay healthy for life.

Dental Emergencies while Traveling

March 22nd, 2023

You’ve planned your dream vacation. Your reservations are made. You’re packed and ready. You’ve even scheduled a dental checkup at our Richmond Hill, ON office to make sure you catch any potential problems, have finished any major work, and have an up-to-date chart.

But things don’t always go according to even the best of plans. So, what to do if you find you have a dental emergency while traveling? Drs.Rashed and Raziee and our team have some recommendations for problems that might arise.

  • Toothache—Rinse your mouth with warm water and use dental floss to remove any food particles. Never put aspirin directly on a tooth or gum tissue. If the pain persists, call a dentist.
  • Cracked or broken tooth—Immediately rinse with warm water to clean the area and apply cold compresses to the face to minimize swelling. Get in touch with a dentist.
  • If you lose a tooth—Keep the tooth moist at all times. Put the tooth back in the socket without touching the root if possible. If that is not an option, place the tooth between the cheek and gums or in milk. See a dentist as soon as possible.

Know where to get help if you need it! If you are traveling in the United States, the American Dental Association offers Find-a-Dentist, a website that can locate a member dentist closest to you. If you are traveling to another country, there are steps you can take to prepare for an emergency.

  • If you are out of the country and need to locate a dentist, your local embassy or consulate, your hotel concierge, or friends abroad can be a useful resource.
  • Before you go, check your insurance to see if you are covered while traveling.
  • If you have travel insurance, find out if it covers dental treatment and can provide information on qualified local dentists and translation help, if necessary.
  • Good dental care is available in many areas internationally, but it is important to know what standards are present in the countries you plan to visit. The Organization for Safety and Asepsis Procedures offers a checklist for safe treatment in their “Traveler’s Guide to Safe Dental Care.”

If you have any questions, Drs.Rashed and Raziee and our team are happy to do all we can to answer them. While it’s unlikely that problems will arise, we are always available if you need to contact our Richmond Hill, ON office. Bon voyage, and we look forward to hearing about your trip!

Sealants: What are they and how do they help?

March 15th, 2023

Molars are made up of canyons, caves, pits, and seemingly endless caverns that are a breeding ground for decay. The protective solution is a sealant. When done correctly, a sealant from Drs.Rashed and Raziee of Smiles on Yonge can be most effective in preventing cavities.

A sealant is made up of composite (a plastic-like) material that contains bonding agents to seal to the edge of the tooth. Sealants placed on the chewing surfaces of back teeth block food from being trapped. The process in which a sealant is placed is quite precise and painless.

First the tooth is cleaned with a sodium bicarbonate (baking soda) spray. Then an acid etch is applied to “roughen up” the surface. No saliva is to touch the tooth. This will re-mineralize the area, then a repeat etching is needed. An alcohol-based liquid then dries out the area and it must remain completely dry. The sealant is placed and guided through all the caverns, pits, fissures, and grooves. It is then cured with a special light, which makes it a hard, plastic-like material.

Sealants can last for several years. It is wise to have them examined on a semi-annual basis. If there is a break in the sealant, a high risk for decay is common. If a sealant is damaged, repair is simple, painless, and quick to complete.

Who can benefit from sealants? Anyone! Children often receive sealants as routine preventive care. Adults with deep canyons with stained grooves on their teeth can also benefit from a sealant. The process is quick, painless, and does not require any anesthesia. It is an effective way to lower dental restorative costs.

An investment in dental sealants can reap great benefits as properly cared for teeth will remain cavity free. Our Richmond Hill, ON location is available to answer your questions so give us a call today!
