What is biofilm?

June 17th, 2026

Biofilm, the protective housing for bacteria, is a hot topic in the medical and dental fields. Routinely taking an antibiotic for a bacterial infection has become more complicated because of biofilm. Bacterial infections may become resistant to antibiotics in part because the biofilm allows for communication among the bacteria, allowing the infection to be sustained.

You’re probably wondering, Drs. Arti and Ashi , what does this have to do with teeth? Since we’re dental professionals, we can tell you why it’s important and what you should know! There is biofilm in your mouth; healthy biofilm and diseased biofilm. Both are made of the same general compounds, but when combined with certain amino acids and cellular chemicals, the diseased biofilm conquers and destroys.

Periodontal disease, otherwise known as gum disease or pyorrhea, is a biofilm disease. If you are undergoing treatment for gum disease and you do not continue with the treatment plan the disease will progress and/or spread due to the biofilm.

There are several ways to treat diseased biofilm. But remember, antibiotics cannot touch the bacterial infection if the biofilm is established.

When your exam is complete, the Ultrasonic or Piezo Scaler should be used. This method of spraying water disturbs the biofilm and provides an opportunity to treat the infection causing bacteria.

Remember, we all need healthy biofilm. Just as your skin protects your body, biofilm housing good bacteria protects your body. The bacteria in the biofilm replicate every twenty minutes. If your body has healthy bacteria, low levels of hydrogen peroxide are produced by the biofilm, preventing harmful bacteria from residing. Harmful bacteria do not like oxygen.

At your exam, we will take measurements around your teeth checking for “pockets”. The higher the number, the deeper the pocket giving more room for harmful bacteria where there is no oxygen. Ask what your numbers are and be involved in restoring your healthy biofilm.

Can You Repair Your Tooth Enamel?

June 10th, 2026

There are lots of ads out there for toothpastes that claim to repair damaged tooth enamel.

Can you treat cavities and tooth decay at home? Well, mostly, no, you can’t.

Can you strengthen your enamel at home? Very possibly—in some circumstances. Let us explain!

Cavities and tooth decay start forming when the enamel on the tooth’s surface breaks down. To discover what causes this breakdown, we need to see how chemistry works with our biology.

Tooth enamel is mainly made from calcium and phosphate ions. These minerals combine to form hydroxyapatite, crystals which make up around 95% of our enamel. Hydroxyapatite crystals are so strong that tooth enamel is the hardest part of our bodies. What can weaken a substance this strong?

Acids. Acidic foods and drinks, as well as acids created by the bacteria in plaque, strip away calcium and phosphate ions in enamel, weakening the surface of the tooth. This is a process called demineralization, and it’s the first stage of tooth decay. Left alone, weak spots will become bigger and deeper until they form cavities.

And tooth enamel, unlike the rest of your body, isn’t living tissue. It can’t regenerate. Once bacteria and acids have created a deep enough cavity, only Drs. Arti and Ashi can repair it by removing decay and filling the tooth.

Wait, this sounds a lot more like “No, you can’t repair your enamel” and much less like “It’s possible to strengthen your enamel.” But we’re not through!

Demineralization doesn’t equal cavities—yet. Careful attention to your habits and your diet can make a difference in whether your enamel continues to weaken or becomes stronger.

Our body’s first defense against demineralization is saliva. Calcium and phosphate ions in saliva bathe the teeth throughout the day, restoring the minerals which have been lost. This is called remineralization. Saliva also helps neutralize acids from the foods we eat. But with a diet heavy in acids, or a lot of plaque buildup, saliva just can’t keep up with the damage.

That’s where “enamel-repair” toothpastes come in. Toothpastes are available that contain hydroxyapatite to restore calcium and phosphates to weakened enamel. But for many of the most common enamel-repair toothpastes, the not-so-secret secret to their effectiveness is fluoride.

Dentists recommend fluoride toothpastes for several very good reasons. Fluoride is attracted to the minerals in tooth enamel and bonds with them. Once bonded, fluoride attracts the calcium and phosphate ions in saliva, helping restore lost minerals to the enamel. Even better, when fluoride bonds with the calcium and phosphate in our enamel, fluorapatite is created. This is a crystal even stronger and more acid-resistant than hydroxyapatite.

If you’re concerned about the strength of your enamel, and especially if you notice any signs of acidic erosion, talk to our Issaquah dental team right away. Drs. Arti and Ashi can:

  • Recommend over-the-counter toothpastes or professional fluoride applications to help reverse early demineralization
  • Provide dental bonding, a crown, or a veneer to protect a tooth with serious erosion
  • Treat a cavity caused by more advanced tooth decay.

Keeping your enamel healthy at home can take many forms. By careful brushing and flossing to remove plaque, by watching the acids in your diet, by making sure you’re properly hydrated, and by using fluoride toothpaste, you can both reduce the risk of demineralization and help restore weak spots in your tooth enamel.

So, can enamel-repair toothpastes effectively repair your teeth? Yes, they can be effective—if demineralization is in its early stages and if you make them a regular part of your daily dental routine.

Warming Up for Summer Weather

June 3rd, 2026

The barbecue’s fired up. T-shirts and shorts are back in style. Sandy beaches and sidewalks are sizzling. Summer’s officially here, and it’s time to get back into hot weather mode. This means getting back into some healthy summer habits.

Be Ready to Hydrate!

Warm weather can lead to dehydration before you know it. And water does more than hydrate—it rinses away food particles after eating or snacking, neutralizes enamel-eroding acids in the mouth, and helps us keep up healthy levels of saliva. 

  • A reusable water bottle is a summer shopping list must. When you’re out walking, hiking, exercising, or camping, you can’t always be sure you’ll have fresh water available. Fill your water bottle before you leave home—you’ll help yourself stay hydrated, save money, and protect the environment, too!
  • Go light on the sports drinks and sodas when planning your summer menus. They’re often filled with sugars and acids—two very unhealthy ingredients for your teeth. 

Restock Your Sunscreen

Sunscreen helps protect skin of all shades and all ages. Exposure to ultraviolet rays is known to cause skin cancer and premature aging. Lip tissue is thin and delicate, especially at risk from the sun’s damaging UV rays. 

  • Check your sunscreen for its expiration date. Protective sunscreens and lip balms lose effectiveness once that date has passed.
  • Some sunscreens are designed for use on lips. If yours isn’t, look for a protective lip balm. All of your sunscreens and balms should have an SPF (Sun Protection Factor) of 30 or higher.
  • Bring your sunscreen and balm with you when you’re out and about, and reapply every two hours, or sooner if you’re eating, drinking, or getting wet.

Prep for Summer Adventures

If you’re travelling this summer, make sure the right dental supplies are part of your gear. A travel size toothbrush and toothpaste, a well-ventilated toothbrush case, dental floss, and your dentist’s emergency contact information are basic necessities. Once you have the basics, you can tailor your kit to your summer plans:

  • Flying? Make sure every liquid, gel, or aerosol you’ll need is the proper size for carry-on flight rules, 3.4 oz (100 ml) or less. Toothpaste and mouthwash are included in these categories, so look for travel sizes in your favorites. 
  • Going overseas? Don’t forget plug adaptors or voltage converters if needed for your electric toothbrush.
  • Camping? An emergency kit with cotton rolls, over-the counter pain relief, oral pain relief gel, dental wax (for damaged braces or a broken tooth), and even temporary fillings and a tooth preservation kit can be crucial in case of unexpected dental injuries.

Make Sure Dental Care Is on Your Summer Calendar

Laid-back summer days are the best, but laid-back dental care really isn’t! Follow your healthy dental routine even during the lazy days of summer.

  • Keep up with your brushing and flossing—brush two minutes twice each day with a fluoride toothpaste, and floss at least once a day.
  • If you’re planning a trip, don’t ignore warning signs. If you have tooth pain or sensitivity, see your dentist to treat any problems before you’re cruising at 30,000 feet or enjoying a remote campout miles from anywhere.
  • Make sure you keep up with your scheduled exams and cleanings. That’s the best way to ensure year-round dental health!

Whether you’re basking in the warm outdoor weather, relaxing in the shade with a cool drink and a good book, on the road to adventure, or wherever your summer plans take you, we hope these easy tips will help you create a summer filled with bright, healthy smiles.

Flossing Fact or Flossing Fiction?

May 27th, 2026

Somewhere in a bathroom drawer or medicine cabinet, we all have one—that little plastic dental floss dispenser. And whether you use your floss every day (yay!), or have completely forgotten it was in there (not so good), just how much do you know about that sturdy string? Let’s find out!

  • Flossing has been around for hundreds of years.

FACT: It’s been just over two hundred years since Dr. Levi Spear Parmly, a dentist in New Orleans, suggested his patients use waxed silk thread to clean between their teeth. This is considered the first “official” invention of dental floss, although using some form of tool to get rid of food particles between the teeth has been around since prehistoric times.

  • Brushing well is the same as flossing.

FICTION: It’s really not. While brushing does a great job of cleaning food particles, plaque, and bacteria from your enamel, there are some places those bristles can’t… quite… reach. Floss was designed to clean plaque and food from between the teeth and close to the gum line where your brush doesn’t fit.

  • There’s more than one way to clean between your teeth.

FACT: Indeed there is! Not only are there many varieties of dental floss (waxed, flavored, round, flat, thick, thin, in a dispenser, attached to miniature floss wands), but you have alternatives if using any kind of floss is difficult for you. Water-flossers direct a pulsing stream of water between and around the teeth and gum line to remove food particles and plaque. Another useful alternative is the interproximal brush, a tiny little cone-shaped brush designed to remove food and plaque from those hard-to-reach spots.

  • Flossing helps prevent gum disease.

FACT: Scientific studies haven’t provided definitive answers. But Drs. Arti and Ashi and our team strongly recommend daily flossing as one of the most important things you can do to prevent gum disease. Gingivitis, or mild gum disease, is caused by irritated, inflamed gum tissue. Gum tissue becomes irritated and inflamed as a response to the bacteria, plaque, and tartar, which stick to your teeth. Anything you can do to help remove these irritants will reduce your risk of gum disease.

  • Flossing helps prevent cavities.

FACT: We strongly recommend daily flossing to remove the food particles and plaque, which lead to cavities. Brushing removes cavity-causing plaque from the outer surfaces of your teeth. But there’s a lot of enamel between your teeth as well. Flossing removes plaque from these hidden spots, helping to prevent interproximal (“between the teeth”) cavities from forming.

  • Bleeding when you floss is normal.

FICTION: Bleeding isn’t a typical reaction to flossing. Bleeding gums could be an early sign of gum disease caused by plaque and tartar buildup. On the other hand, if you floss too hard, or go too deeply below the gum line, you can make delicate gum tissue bleed. Ask Drs. Arti and Ashi for tips on perfect flossing technique.

  • You need to floss after every meal.

FICTION: Dental professionals generally recommend brushing twice a day and flossing at least once each day. But this suggestion comes with some exceptions. If you have braces, your orthodontist might recommend flossing after eating. And certainly, for removing pesky food particles, flossing or interdental picks are a sensible choice after any meal.

  • Your dentist will never know that you haven’t been flossing.

FICTION: Nope. Sure, you can miss flossing a few times and catch up before your appointment at our Issaquah office. But built-up plaque between the teeth, red, swollen, or bleeding gums, and gingivitis and interproximal cavities let both you and Drs. Arti and Ashi know that you’ve been neglecting good dental habits.

  • It’s never too late to start flossing!

FACT: Flossing is a simple, quick, and inexpensive way to maintain tooth and gum health. If you haven’t had much luck flossing in the past, ask Drs. Arti and Ashi for flossing tools and techniques that will work for your specific needs. Start now, and see what a difference it will make at your next checkup!

If you had all these flossing facts at your fingertips, congratulations! But if you didn’t, no need to worry, because the real test of your knowledge is in its application. Flossing properly at least once each day will give you something far more rewarding than blog-quiz kudos—you’ll see that regular flossing rewarded with healthier teeth and gums!
