Falling Into Cold and Flu Season

November 4th, 2026

There are many reasons why people love autumn in Kanata, Ontario. Crisp air. Jeweled leaf tones. Reuniting with school friends. Fall sports. Halloween and Thanksgiving.

But there’s one thing about autumn which never appears on anyone’s favorites list: it’s the start of cold and flu season. If you’ve fallen ill, we have some ideas for taking care of yourself—and your dental health—as you recover.

  • Stay Hydrated

Proper hydration is vital for healthy skin, temperature, digestion, and other bodily functions. Sweating, fever, diarrhea, and vomiting—common symptoms of colds or flu—cause dehydration.

Dehydration also creates problems for your oral health. Hydration ensures healthy levels of saliva. Saliva helps prevent cavities by washing away bacteria and food particles and neutralizing oral acidity. Saliva bathes the teeth in minerals which keep tooth enamel strong. Hydration also supports healthy bone and connective tissue, which encourages faster orthodontic healing as your teeth move into their ideal positions.

Even if you don’t feel like eating when you’re ill, be sure to drink the liquids you need to stay hydrated. For your dental health, try to avoid overdoing sugary beverages and acidic drinks.

  • Eat Healthy Foods

It’s always a good idea to eat nutritious foods, but it’s especially important when you’re not feeling well. Fatty and greasy foods are hard to digest. Processed, sugary, and fast foods filled with empty calories don’t provide the protein and nutrients which can encourage a speedier recovery. And studies suggest that sugar-filled foods can suppress your immune system, the network of cells and organs working together to prevent and fight infection.

A diet rich in proteins, vitamins, and minerals will help you recover when you feel up to regular meals again. Foods which contain nutrients like calcium, phosphorus, and vitamin D are necessary for healthy teeth. Vitamins A and C are essential for gum health and bone density, which is especially important while you’re in orthodontic treatment.

  • Minimize Exposure to Germs—For Yourself and Others!

To help prevent catching colds and flu, be mindful that viruses and bacteria can live for hours and even days on non-porous surfaces like phones, keyboards, and doorknobs. Washing your hands with soap and water before touching your mouth, nose, or eyes, before brushing and flossing, and before you cook and eat will help you eliminate most of the germs which cause colds and flu.

If you do catch something, be mindful of your interactions with others. You can help stop the spread of germs by limiting contact with other people, masking, and covering your mouth and nose when you sneeze or cough.

Protect yourself and those around you by being careful with dental hygiene. Never share your toothbrush with others. Don’t let toothbrushes touch in a common container. Always let your toothbrush air-dry since germs prefer moist environments.

And, while it’s unlikely that you’ll re-catch a cold from your toothbrush, brushes are only at their best for three to four months. If yours is past its prime, post-illness is a perfect time to replace your old brush with a clean new one.

  • Be Choosy with OTC Medicine

Many cough syrups and cough drops are filled with sugar. Consider sugar-free syrups, or, if you use cough or cold medications which include sugar, rinse or brush afterward.

Look for sugar-free cough drops, which won’t bathe your enamel in sugar as they dissolve. And never crunch down on cough drops. A chipped tooth, cracked enamel, a broken bracket, or a warped wire certainly won’t make you feel better!

  • Keep Up with Your Brushing and Flossing

Even when you feel weak and tired, it’s important to brush and floss as usual—with one exception.

Vomiting brings up harsh stomach acids which weaken the mineral bonds keeping tooth enamel strong. Brushing right away can spread these acids around your mouth and your enamel. If you vomit, rinse your mouth with water and wait 30 minutes before brushing to allow your enamel to come back to full strength.

  • Stay Home When You’re Sick

You’ll get better faster when you take care of yourself, which includes getting the rest you need to recover. And beyond doing something for your own health, you won’t be risking the health of the people around you.

If you have an appointment scheduled with Dr. Razavi, reschedule as necessary. Your orthodontic team at Palladium Orthodontics will be happy to accommodate you to prevent the spread of colds and flu and to make your appointment a more comfortable one.

Don’t let cold and flu season ruin one of the most beautiful times of the year! Follow your doctor’s advice, take good care of yourself when you’re ill, and visit Dr. Razavi again once you’re feeling better to keep your treatment on track.

Don’t let braces ruin your Halloween

October 28th, 2026

Halloween is a time to enjoy delicious candies you might avoid the rest of the year. Youngsters who get to dress up and ask for sweet treats out trick-or-treating cherish this holiday.

If you have braces on, Dr. Razavi would like you still to have fun and celebrate Halloween this year!

It’s easy to get carried away on Halloween by eating too much candy at once. Most parents try to prevent the all-too-common sugar high their kids experience on Halloween night. While there are certain candies that should be avoided, not all candy will cause problems for kids with braces. After trick-or-treating, you could trade unsafe candies with siblings and/or friends so they don’t miss out on the sugar buzz.

Dr. Razavi and our team have come up with a list of teeth-friendly treats that should keep you from worrying about breaking your braces. We also came up with a list of candies to avoid, so as to save you a trip to our Kanata, Ontario office. Remember to be extra careful when you indulge this Halloween!

Braces-Friendly Sweets

  • Solid chocolate: Milk, white, or dark
  • Nougat-filled candy bars: Three Musketeers
  • Powdery candy: Sweet Tarts, Pixie Stix
  • Mint-flavored candy
  • Malted milk balls
  • Soft cookies
  • Peanut butter crackers

Avoid These Treats

  • Sticky candy: Starbursts, toffee, Tootsie Rolls
  • Hard candy: Suckers, Jolly Ranchers
  • Taffy
  • Caramels
  • Fruit chews
  • Gum
  • Caramel apples
  • Skittles
  • M&Ms

When in doubt, ask Dr. Razavi if a particular candy is safe to eat when you have braces. We hope you enjoy your Halloween sweets, and look forward to seeing you at your next appointment! Happy Halloween!

Electric Toothbrushes vs. Regular Toothbrushes

October 21st, 2026

Convertible or sedan? Downtown or suburbs? Electric or manual toothbrush? As life decisions go, it’s certainly not choosing your next car, or deciding where you want to live. But, even when you are selecting a toothbrush, it helps to make a list of the pros and cons of the contenders before you make that final selection.

  • Efficiency

The most important factor in choosing a toothbrush is finding out which model works best to eliminate bacteria and plaque. And studies have shown that, used properly, both electric and manual toothbrushes do a great job of removing plaque. Some electric models can reach the backs of teeth and the gumline more easily, some manual head designs work better for your individual mouth and teeth, so your particular needs should dictate which style of toothbrush you use. Talk to us about the best methods to brush with your preferred toothbrush, and we’ll let you know if one type of toothbrush or the other might work better for you.

  • Health Considerations

Brushing too energetically can actually harm teeth and gums, causing sensitivity and damage to the enamel and gum tissue. An electric toothbrush should provide a continuous brushing motion without needing any pressure from the brusher. This might be the model for you if you have a too-vigorous approach to brushing, or sensitive teeth and gums.

An electric toothbrush can also be more efficient for older and younger brushers, those with limited mobility, and those with health conditions or injuries that make brushing with a regular toothbrush more difficult.

  • Cost

An electric toothbrush is not a one-time investment. You should change the removable head as often as you change your manual toothbrush (every three to four months, please). But this cost is offset if an electric toothbrush is more efficient in removing your plaque, easier to use, or even if you just prefer it to manual brushing. If you find that you brush better and more often with an electric toothbrush, the added expense is well worth it.

Whichever brush you decide on, the most important part of the brush is the person holding it! A regular appointment with your toothbrush for two minutes of thorough brushing in the morning and two in the evening, daily flossing, and regular visits to our office for checkups and cleanings will keep your teeth healthy and strong no matter which toothbrush you choose.

Questions about your toothbrush choices? Don’t hesitate to ask Dr. Razavi at our Kanata, Ontario office.

How to Avoid Delays During Your Orthodontic Treatment

October 14th, 2026

Our patients at Palladium Orthodontics hate the thought of delaying their treatments and often ask us what they can do in between their adjustment visits to help. Today, Dr. Razavi and our team thought we would provide some tips on how you can stay on track in regards to your treatment plan time.

The first thing we want you to do is keep your adjustment appointments. Each visit with Dr. Razavi is carefully planned to move your teeth a specific way in a certain time frame. It’s important to note that missing an appointment can add weeks or months to your treatment time.

Next, we want you to let Dr. Razavi and our team know right away if your experience any problems with your braces or appliances. A missing wire, rubber band, or broken bracket can delay treatment time, so we ask that you please give us a call right away to report any issues rather than waiting until your next visit.

Make sure you wear your rubber bands as prescribed by Dr. Razavi. Most, if not all, of our patients will need to wear elastics or rubber bands at some point during their treatment. Not wearing the bands or elastics, or not wearing them enough, can slow down your treatment time. Rubber bands are critical in aligning your bite and are important for the bite-fixing phase of your treatment.

Finally, we want you to maintain good oral hygiene, just as you did before your treatment began. In addition to flossing regularly, we encourage you to brush your teeth several times a day. Not brushing will allow sugar to wear away the cement on the braces, making them less effective in moving your teeth, as well as elevate your risk of developing cavities or tooth decay, which will inevitably delay treatment time.

If you have any questions about any of these tips, or if you have any general questions about your treatment, please give us a call at our convenient Kanata, Ontario office, or ask Dr. Razavi during your next adjustment visit!
