Xylitol: A significant factor for improving your oral health

March 4th, 2026

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 Johnson Orthodontics. We look forward to seeing you soon!

How NOT to Forget Your Retainer

February 25th, 2026

The alarm sounds in the morning, you wake up and realize "I forgot to wear my retainer!"

If this only happened once, don't panic. Missing one night with a retainer is unlikely to cause significant teeth movement. However, if it has happened often, give our Columbus, OH office a call to make sure your teeth haven’t shifted position.

Here are some tips from Dr. Dennis Johnson to help you remember your retainer:

1. Write down the instructions we give you for wearing the retainer, whether you should wear it all day or at night, or just a few times a week. Writing things out like this helps set the schedule in your memory.

2. Clean the retainer when you take it out each time. If you don’t you may not have time when you’re rushing to get to work or school to clean it properly and may be tempted not to wear it.

3. Put a note on your mirror or in your purse or wallet reminding you to wear your retainer.

4. Set an alarm on your mobile phone to remind you when it’s time to put the retainer in. If you have email with a calendar you can set up daily reminders, too.

5. Always put the retainer in its case when you take it out to eat or sleep. You’ll reduce your risk for losing it or accidentally throwing it away.

6. If you don’t have to wear the retainer every day, you can use some recurring events to help you remember. With this system for example, watching your favorite weekly TV show, laundry day, or family pizza night can all serve as reminders that you should put in your retainer.

7. Don’t be shy about asking for help if you’re forgetful. Assure your spouse, parents, siblings, or roommates that you won’t consider if nagging if they remind you to wear your retainer.

8. Surf online for examples of how teeth can shift when retainers are not properly used. Those stories can serve as timely warning not to let the same thing happen to you!

Remember, you can always call our Columbus, OH office if you feel your retainer is uncomfortable or painful. We'll work with you to protect your smile!

The Evolution of Braces

February 18th, 2026

Did you know that even in ancient times, people wanted to improve the look and function of their smiles? Johnson Orthodontics thinks of modern orthodontic appliances as sleek, efficient technology, but this was not always so! Take a look at the highlights in the evolution of braces.

Ancient Times: From Greece to Rome

  • According to The Angle Orthodontist, Aristotle and Hippocrates first thought about methods for straightening teeth between 400 and 300 BC.
  • The Etruscans, in what we now know as Italy, buried their dead with appliances that maintained spaces and prevented collapse of their teeth and jaws during life. Archaeologists have discovered mummified remains in various locations that have metal bands wrapped around the teeth.
  • A Roman tomb has also been discovered in which the teeth were bound with gold wire, including documentation on the wire’s use as a dental device.

18th Century: A French Development

  • The French dentist Pierre Fauchard is acknowledged as the father of modern dentistry. In 1728 he published a book that described various methods for straightening teeth. Fauchard also used a device known as a “blandeau” to widen the upper palate.
  • Louis Bourdet was another French dentist who published a book in 1754 that discussed tooth alignment. Bourdet further refined the blandeau and was the first dentist to extract bicuspids, or the premolar teeth between canines and molars, for the purpose of reducing tooth crowding.

19th Century: Orthodontics Defined

  • Orthodontics started to become a separate dental specialty during the early 19th century. The first wire crib was used in 1819, marking the beginning of modern orthodontics.
  • During this period, gold, platinum, silver, steel, gum rubber, vulcanite, and occasionally wood, ivory, zinc, and copper were used — as was brass in the form of loops, hooks, spurs, and ligatures.
  • Edward Maynard first used gum elastics in 1843 and E. J. Tucker began making rubber bands for braces in 1850.
  • Norman W. Kingsley published the first paper on modern orthodontics in 1858 and J. N. Farrar was the first dentist to recommend the use of force over timed intervals to straighten teeth.

20th Century: New Materials Abound

  • Edward Angle developed the first classification systems for malocclusions (misaligned teeth) during the early 20th century in the United States, and it is still in use today. Angle founded the American Society of Orthodontia in 1901, which was renamed the American Association of Orthodontists in the 1930s.
  • By the 1960s, gold was universally abandoned in favor of stainless steel.
  • Lingual braces were the “invisible” braces of choice until the early 1980s, when tooth-colored aesthetic brackets made from single-crystal sapphire and ceramics became popular

Today

As we arrive in the present, you need only look at your own braces to see how far we’ve come. Your treatment plan was probably created with a 3D digital model, and we’ve likely used a computerized process to customize your archwires. Perhaps you have clear aligners, self-ligating brackets, or highly resilient ceramic brackets with heat-activated wires.

Orthodontics has come a long way from the days of Aristotle, and even the bulky wrap-around braces of just 60 years ago. Regardless of your specific treatment plan, the development of high-tech materials and methods has made it possible for your orthodontic experience to be as effective, efficient, and comfortable as possible.

When should I floss during the day?

February 11th, 2026

A vital step in your oral health routine is flossing. We hope our patients at Johnson Orthodontics maintain good oral hygiene, including daily flossing between each visit to our Columbus, OH office. A toothbrush is not always enough to get to the hard-to-reach areas of your mouth. When food remains between your teeth, bacteria starts to grow and will break down your enamel. This is where flossing comes in!

Should you floss before or after brushing?

Whatever your personal preference, you may floss before or after you brush your teeth. When you floss first, you can brush away any leftover dislodged food debris from your teeth. On the other hand, when you brush first, you will loosen the plaque between your teeth, which makes flossing more effective.

The essential aspect is that you floss thoroughly by using a fresh strand of floss and make sure to get between every tooth. Even if your teeth look and feel clean, don’t skip flossing or plaque will begin to build up on your teeth.

When is the best time to floss?

Although you should brush your teeth at least twice a day, Dr. Dennis Johnson and our team recommend flossing your teeth thoroughly once a day. Many people prefer to floss before bed, so that plaque doesn’t sit between their teeth all night.

What kind of floss should I use?

You may choose between interdental cleaning picks or flexible floss strands to perform your daily flossing routine. If you have permanent oral appliances or restorations, be sure to follow the flossing instructions provided to you.

Do you need help flossing?

If you’re having trouble flossing or have questions about which floss is best for your teeth, contact our Columbus, OH office and we can provide you with support. Be sure to keep up with your daily flossing routine, and we will see you at your next appointment!
