Understanding Cavities

November 9th, 2022

Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Dr. John Zarrella and Dr. Peter C. Rider will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Cold Comfort

November 2nd, 2022

The sounds of the season are filling the air—falling leaves rustling along the sidewalk, football cheers, holiday greetings—and the coughs and sneezes of your fellow sufferers. Yes, it’s cold and flu season, and you’re one of the unfortunate people who’s caught whatever it is that’s been going around. While you’re recuperating, here are some tips for looking after yourself and your dental health.

  • Keep Hydrated

Fevers, sweating, diarrhea, and vomiting can all lead to dehydration. You know how serious that can be for your overall health, but it also leads to problems for your oral health. Lowered saliva production puts you at an increased risk for cavities, since saliva washes away food particles and bacteria, neutralizes cavity-causing acids, and helps strengthen tooth enamel. In addition to the dehydration illness can cause, many over the counter medications leave your mouth dry as well. Be sure to drink fluids throughout your illness, and, as always, try to avoid sugary beverages and acidic drinks.

  • Keep Up Your Dental Hygiene

You may feel like you never want to get out of bed again, but it’s important to maintain your dental routine. Brushing and flossing are still necessary to protect your teeth and gums. And try gargling with warm saltwater or a mouth rinse. You’ll not only soothe a sore throat and help prevent the bad breath that sinus problems can cause, but you’ll also reduce oral bacteria and plaque.

  • Keep Away from Your Toothbrush after Vomiting

Even though cleaning your mouth and teeth might be the first thing you want do to after throwing up, wait at least half an hour before brushing your teeth. Cavities occur over time when tooth enamel is weakened by the acids oral bacteria produce. When you vomit, your teeth are exposed to much stronger stomach acids, and immediate brushing simply brushes these acids on to your enamel. One common recommendation is to mix a teaspoon of baking soda with a glass of water, swish it around your mouth, and spit it out. Or simply use a glass of plain water, and repeat if needed.

  • Keep Your Cough under Control

Here’s a tip your family, friends, co-workers, and fellow public transportation users will thank you for: If you are sick, stay home. If you do find yourself coughing while around others, cover your mouth. Cough into a tissue instead of your hands or the open air. If you don’t have a tissue available, cough into your upper sleeve.  And while you’re protecting others, protect your tooth enamel. Replace overly sweet cough syrups with tablets, and, if you are using cough drops, remember that sucking on a sugary cough drop is like sucking on candy. Look for the sugar-free variety and use only as directed.

  • Don’t Keep Your Toothbrush

Now that you’re feeling better, it might be time to throw out your toothbrush. The chances of re-infection are low (unless you have a compromised immune system), but we often hang on to our toothbrushes long after their effective days are past. A toothbrush should only last around three to four months. If yours is older than that, this is a perfect opportunity to replace a brush that might be getting a bit long in the tooth with a fresh, germ-free model.

Above all, be good to yourself when you are ill. Drink healthy fluids, maintain your dental routine, and treat your teeth and your body with care. Here’s wishing you a speedy recovery, continuing dental health, and a season filled with beautiful smiles.

Why You Should Avoid Energy and Sports Drinks

October 26th, 2022

In a world where everything moves so quickly and teens and young adults find themselves pulling “all-nighters” or working long hours, energy drinks have grabbed the spotlight. You’ll have one (or three) and suddenly you have the drive you need to keep going.

The same can be said for sports drinks. It’s common for people to have one even when they’re not engaged in any strenuous physical activity, which is what they were designed for. People will drink them simply because they’ve grown to love the taste.

Although they might taste great and boost your energy, there’s a serious down side to consuming energy and sports drinks on a steady basis. Studies have shown that these drinks contain so much acid that they start to destroy your teeth after just five days of consistent use.

The acid in these drinks destroys your tooth enamel, which makes your teeth more vulnerable to bacteria. This can progress to staining, tooth decay, and hypersensitivity.

That’s why Dr. John Zarrella and Dr. Peter C. Rider and our team want to encourage you to try to limit the amount of sports and energy drinks you consume. If you do enjoy either or both of these drinks, you should make it a habit to rinse your mouth with water immediately after consumption, and brush your teeth about an hour later, after the period when acid has a softening effect on your enamel has passed.

If you feel like you’re already experiencing the side effects of heavy energy and sports drink consumption, visit our Ashland office, and our team can provide solutions for how to prevent further damage from occurring. It’s never too late to change a bad habit!

Dental X-Rays: Are They Safe?

October 19th, 2022

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Dr. John Zarrella and Dr. Peter C. Rider and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.
