The Purpose of a Dental Crown

August 11th, 2026

A dental crown, otherwise known as a cap, covers an infected tooth and can vary in function, depending on the position of the tooth. Crowns cover all the visible parts of a tooth and vary in size, appearance, and functionality.

A crown can be used to protect a weak tooth from breaking, hold together an already broken or worn tooth, cover the tooth with a large filling or dental implant, hold a dental bridge in place, or support a cosmetic modification.

Several types of crowns are available, depending on the tooth to be treated. Stainless-steel crowns are used on permanent teeth, usually as temporary measures in children because they’re more cost-effective for baby teeth that naturally come out over time.

Metal crowns are another option that includes gold alloys, or base-metal alloys. Metal crowns are notable for their ability to withstand biting forces, rarely break or chip, and therefore offer the best results in terms of normal wear and tear.

Porcelain fused to metal crowns most closely resemble a normal tooth and are a good choice for front or back teeth. Other, less common types include all-resin, all-ceramic, all-porcelain, and zirconia crowns.

If you’re getting a crown, you can expect a few things during your visit with Drs. Coombs, Holmes, and Johnson. Crown placement usually requires two appointments. The first entails preparation to get an impression of the tooth, shape it, and place a temporary crown. The impression is sent to a lab where a technician makes the crown to be fitted.

During the second appointment, the high-quality porcelain crown is placed on the problematic tooth.  

If you notice any signs of discomfort in your mouth, always let Drs. Coombs, Holmes, and Johnson know by calling our Spokane, WA office. We will determine which type of crown is best for your tooth to give it the added strength it needs. Crowns can be very helpful for your oral health if you have any teeth that need extra support.

Hot Day? Three Drinks to Leave Home When You’re Packing the Cooler

August 4th, 2026

Whew! It’s a hot one! And whenever the temperature soars, you need to stay hydrated, especially when you’re outside or exercising. But all cold drinks aren’t equal when it comes to healthy hydration. Which beverages shouldn’t have a prime spot in your cooler when you’re wearing braces or aligners?

  • Soft Drinks

You’re probably not surprised to find soft drinks at the top of the list. After all, sugar is a) a big part of what makes soda so popular, and b) not a healthy choice for your teeth.

Sugar is a favorite food source for the oral bacteria that make up plaque. These bacteria convert sugar into acids, and these acids attack the surface of your tooth enamel. Over time, the minerals which keep enamel strong begin to erode, and weakened, eroded enamel is a lot more susceptible to cavities.

So, what about sugar-free drinks? Does this make soft drinks a better choice? Unfortunately, you can take the sugar out of many sodas, but you can’t take the acids out. Most soft drinks are very acidic, even without sugar, and will cause enamel erosion just like the acids created by bacteria will.

  • Fruit Drinks

Fruit juice provides us with vitamins, which is great, but it’s also full of natural sugars and acids. And blended fruit drinks and fruit punches often contain added sugars and added citric acids. Best to choose 100% fruit content and check the labels before you buy. (And you can always get refreshing fruit flavor by adding a slice of fruit to a glass of water.)

  • Sports Drinks

You might be surprised to see these on the list—after all, they promise healthy hydration while you’re working out. And hydration is healthy—but sugars and acids aren’t. Even when the label tells you there’s no added sugar, that same label will often reveal high amounts of citric acid. In fact, some sports drinks are more acidic than sodas.

We’ll make an exception, though, for thirsty people who participate in sports or activities that require a lot of physical exercise and produce a lot of sweat. When we sweat, we lose electrolytes, those ionized minerals which help regulate many vital bodily functions. Talk to Drs. Coombs, Holmes, and Johnson about which sports drinks are best for you if you need to replenish your electrolytes when working out.

So, what’s your best hydration choice on a hot day? Water! It not only hydrates you, it cleans your teeth, it helps you produce saliva, and it often contains tooth-strengthening fluoride. But if you only have sports drinks in the cooler, or if you just want to enjoy a soft drink or a bottle of juice from time to time, no need to go thirsty. We have some ways to make sure your teeth are safer, even with this tricky trio:

  • Rinse with water after you drink a sugary or acidic drink. And remember to brush when you get home.
  • Be choosy. Check labels for added sugars and acids.
  • Don’t sip your drinks all day long. Saliva actually helps neutralize acids in the mouth, but sipping acidic beverages throughout the day doesn’t give saliva a chance to work.
  • Use a straw to avoid washing your enamel in sugars and acids.

You need to keep hydrated when it’s hot. When you’re packing your cooler, choose drinks that are healthy for your entire body, including your teeth and gums. Ask our Spokane, WA team for the best choices in cold drinks to make sure you’re getting the hydration you need—without the sugar and acids you don’t!

Just What Is Plaque?

July 28th, 2026

When you were younger, and you brushed your teeth without any help for the first time, it was a big step. It meant you’d learned the right way to brush to keep your teeth and gums healthy. But why does brushing help keep you healthy? Let’s talk about plaque!

  • What Is Plaque?

Plaque rhymes with “attack,” and that’s just what it does to your teeth. If you don’t brush for a few days (which is a bad idea!), plaque is the reason for that fuzziness you feel when you run your tongue over your teeth.

If your teeth feel fuzzy, that means that plaque has been building up for a while. But how does it begin?

Plaque is made up of saliva, bits of food, other liquids, and tiny little organisms called bacteria. While most of the bacteria in our bodies don’t bother us—and some even help us—the bacteria in plaque are not so helpful.

Plaque starts with a type of bacteria that stick to the teeth, loosely at first, and then more strongly. Within hours, they join with saliva, bits of food, and other bacteria and bacterial products to make a very sticky film. This film is plaque.

Why is it so important to brush plaque away every day? As Drs. Coombs, Holmes, and Johnson will tell you, plaque can cause cavities and hurt your gums.

  • How Does Plaque Cause Cavities?

Bacteria are like us—they need food. The bacteria in plaque especially like the sugars we eat. (That’s why you shouldn’t have too much junk food or candy in your diet.) Bacteria change these sugary building blocks into a kind of acid, and because plaque is sticky, the acids stay on your teeth.

These acids breaks down the enamel, that hard coating which covers teeth. Tiny weak spots can grow and become holes in the enamel. We call these holes cavities, and your dentist can repair them by cleaning away the decay and putting a filling in your tooth to protect it.

But it’s best to prevent cavities from ever starting by brushing and flossing. Even though plaque is sticky, it is easy to brush away when you do it every day.

  • How Does Plaque Hurt Your Gums?

The gums surround our teeth and help protect them, but they are also delicate. When plaque builds up, it can irritate your gums.

You might notice that your gums get red, feel sore when you brush, or look puffy. You might have bad breath that doesn’t go away. All these are signs that your gums are reacting to the plaque around them.

The good news is that careful brushing and flossing can usually fix these problems. Talk to Drs. Coombs, Holmes, and Johnson about taking good care of your gums.

  • Can We Fight Plaque?

Yes! From the time you were small and learned how to brush, you’ve been learning how to fight plaque.

  • Brush at least twice a day for two minutes, and be sure to brush all around each tooth and the gums.
  • Floss to remove plaque from where it hides between the teeth and near the gums.
  • Visit our Spokane, WA office for a cleaning, to remove plaque from hard-to-reach places and to learn the best ways to brush and floss.

As soon as you finish brushing, plaque starts to build up again. But no need to worry! Keep brushing, flossing, and visiting us for regular cleanings, and all your careful work will be rewarded will a beautiful, healthy smile.
