Do Spring Allergies Mean (B)Looming Dental Problems?

April 1st, 2026

April showers bring May flowers, and May flowers bring . . . allergies. If you’re one of the millions of people who suffer from seasonal allergies, you might be suffering some dental side effects as well.

When you have pollen allergies, pollen triggers your body’s immune system to release histamines. Histamines are part of the body’s defense system. They cause the tissues in the nose and sinuses to become inflamed and swollen as they increase blood supply to these areas. They also cause your body to produce more mucus.

Normally, mucus from the sinus cavities drains into the nasal cavity and then down the back of the throat, where it mixes with saliva and is swallowed. We never even notice it. Until it’s allergy season. Unfortunately, our defense mechanisms can have some offensively unpleasant consequences.

  • Headache & Facial Pain

Our sinus cavities are small hollow spaces in the bones of the head which are filled with air and, like our nasal cavities, are lined with mucous membranes. It’s these membranes, not surprisingly, which produce mucus. And though we might turn up our noses at this slippery topic, mucus is actually quite helpful for trapping and filtering out unwanted hitchhikers like bacteria, viruses, dust, pollens, and other pollutants in the air we breathe before they reach our lungs.

When histamines are released, normal mucus production increases to filter out those tiny pollen invaders. At the same time, tissue around the nose and sinuses swells up, which can trap mucus inside the sinus cavities. This, in turn, causes increased pressure within the sinuses, and this pressure brings on allergy-related headaches and facial pain.  

  • Nasal Congestion & Postnasal Drip

With the occasional runny nose or sneeze, you can blow your nose once or twice and that’s that. During allergy season, greatly increased mucus production might see you spending all day within reaching distance of your box of tissues. But when the tissue in your nose is swollen as well, you now find yourself with nasal congestion.

A stuffy nose means excess mucus has to exit somewhere else, which means this extra, often thicker, mucus all drains into the back of your throat. This is postnasal drip, and it can make you miserable in several different ways. Hoarseness. Coughing during the day. Worse coughing at night. Sore throat. Nausea. Difficulty swallowing.

All these allergy symptoms are uncomfortable enough! But, to add to our discomfort, allergies can lead to uncomfortable oral symptoms as well.

  • Tooth Pain

A common result of allergies is tooth pain. How does this happen? It’s because of the way our bodies are designed. The maxillary sinus cavities are directly above the roots of our upper molars.

When sinus cavities are congested and sinus pressure builds up, it also puts pressure on these roots. The result is tooth pain, usually affecting several upper molars at once.

  • Dry Mouth

One of the natural responses to a stuffy nose is mouth-breathing—we can’t go without air, after all! But exposing the inside of the mouth to all that air dries out delicate gum and mouth tissues. It also reduces normal saliva flow. This can cause xerostomia, more commonly known as dry mouth.

Because saliva neutralizes acidity in the mouth and washes away bacteria and other germs, lower saliva production means greater risk of cavities, infections, and bad breath. Dry mouth can also cause gum irritation and gingivitis, because less saliva means more harmful bacteria build-up between the gums and the teeth.

  • Antihistamines & Your Oral Health

If histamines are the problem, are antihistamines the obvious solution? This is a good question for Dr. Kelly Peterson or your physician. Antihistamines can be very drying—so you might find you’re experiencing dry mouth even when all those other pesky allergy symptoms have disappeared. And, if you already suffer from xerostomia, it’s especially important to get your doctor’s advice before buying over the counter antihistamines.

In allergy season, just like any other time of the year, be sure to hydrate and keep up with brushing and flossing for fresh breath and healthy teeth and gums. Talk to Dr. Kelly Peterson if you have persistent tooth pain, dry mouth, or irritated gums—it’s always best to rule out other causes like infection or decay.

But, if your problems are caused by allergies, you don’t have to wait until the next snowfall to get relief. Talk to your doctor or allergist for ways to reduce or eliminate your symptoms before allergy problems start blooming into dental problems. You’ll breathe easier!

Dental X-Rays: Are They Safe?

March 25th, 2026

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. Kelly Peterson 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.

Stress and Your Oral Health

March 18th, 2026

Stress symptoms—which include high blood pressure, severe aches, and insomnia—may be affecting your health, even though you might not realize it. You may think illness is the culprit when in fact stress may actually be the reason. While stress can be good for us sometimes, Dr. Kelly Peterson and our team know stress can be physically harmful. But what is often overlooked is that stress can also take a toll on your mouth. Here’s how:

Teeth Grinding

It’s not uncommon for people dealing with stress to develop teeth grinding, also known as bruxism. People who grind their teeth at night may do so unconsciously, but the condition requires treatment to prevent the development of headaches, TMJ, and tooth damage. If you’re a night-grinder, talk to Dr. Kelly Peterson. We may recommend a night guard.

Mouth Sores

Research suggests stress and depression harm your immune system, making it easier for infections to develop and stick around. That can mean canker sores or a cold sore outbreak. If mouth sores are a recurring problem for you, give us a call to schedule an appointment with Dr. Kelly Peterson.

Bad Habits

Stress can lead to bad oral health habits such as smoking, drinking, and neglecting your daily brushing and flossing routine. If you’ve been feeling under pressure lately, try to keep up with your oral health routine—it will serve you well when your stress levels return to normal.

Dr. Kelly Peterson and our team at Northwest Smile Design know there’s not always an easy way to reduce your stress levels, but eating healthy, exercising regularly, and spending time with friends and family are all good places to start.

St. Patrick's Day: Celtic pride, green shamrocks, and lucky charms!

March 11th, 2026

“St. Patrick's Day is an enchanted time -- a day to begin transforming winter's dreams into summer's magic.” Adrienne Cook

Lucky green shamrocks, leprechauns, and pots of gold – it must be St. Patrick’s Day! If you’re not Irish, how do you go about celebrating St. Patrick’s Day? It’s easy: You just put on one of those tall leprechauns hats, dress in green from head to toe, and wear one of those carefree pins that say “Kiss Me, I’m Irish”. On St. Patrick’s Day, everyone is Irish, and that is the universal beauty of the holiday. Celtic pride does not discriminate.

Wondering what our team at Northwest Smile Design is doing to celebrate March 17th? Well, we’ve thought about doing everything from handing out lucky gold coins (you know, the fake ones that are made of chocolate) to shamrock stickers. Maybe we’ll even give away green toothbrushes and floss! You’ll never know unless you come in to see Dr. Kelly Peterson !

All kidding aside, St. Patrick’s Day is an important cultural and religious holiday. There are lavish parades and church services across Ireland on March 17th. Over time, however, the holiday has developed into a day to observe Irish culture in general. In places like England and the United States, where there is a large Irish Diaspora, the holiday has greater significance than other countries. From the streets of Boston to St. Patrick’s Cathedral in New York, it is a day of celebration, and many Americans of Irish descent will cook up a traditional meal of corned beef and cabbage.

So, to all of you with Irish ancestry, and to all of you who have decided to be Irish for the day, our office wishes you a Happy St. Patrick’s Day. Good luck looking for a pot of leprechaun gold, which is said to exist at the end of the rainbow. However, keep away from those sugary Lucky Charms; sweet cereals might taste good, but your kids’ teeth might not be feeling too lucky if they eat it for breakfast every day. Have a great St. Paddy’s Day!
