What is a palatal expander?

November 12th, 2025

Orthodontists like Dr. Byron Diehl recommend a first orthodontic visit and evaluation for your child around the age of seven. We will evaluate your child’s jaw and facial development and make sure that there is enough room in the mouth for the permanent teeth when they arrive. One of the recommendations we might make for early treatment is the use of a palatal expander. If you are unfamiliar with this device, let’s take a closer look at why it’s necessary and what exactly it does.

Why do we recommend the palatal expander?

There are two dental arches, composed of the upper and the lower teeth, in your child’s mouth. This arch-shaped design is meant to accommodate all the permanent teeth. Further, when the upper and lower teeth meet, they should result in a healthy occlusion, or bite.

Sometimes, the upper dental arch is simply too small to accommodate all of your child’s permanent teeth, leading to crowding, extractions, and impacted teeth. Also, a too-narrow arch can result in a crossbite, where some of the upper teeth bite inside the lower ones. An improper bite can lead to problems such as TMJ (temporomandibular joint) disorder, improper wear and stress on teeth, certain speech difficulties, and other potential complications. The palatal expander was designed to prevent these problems from occurring.

What is a palatal expander and how does it work?

The expander itself is a device that increases the size of the upper dental arch. Before your child’s bones are finished growing, the space between the two bones of the upper palate is filled with cartilage. This tissue is flexible when children are young, but gradually fuses solidly into place by the time they are finished growing (usually in the early to mid-teens). If the arch can be widened to accommodate the emerging permanent teeth, or to reduce malocclusions, this improvement can also affect the need for, and length of, future dental work.

There are several types of expanders available at our Redlands, CA office. These are custom-made appliances, commonly attached between the upper teeth on each side of the jaw. The two halves of the device are connected with a screw-type mechanism that can be adjusted to widen the upper palate and dental arch with gentle pressure. This is a gradual process, with small adjustments usually made once or twice a day to slowly move the bones further apart. As weeks go by, you will notice a successful change in the spacing of the teeth. Your child might even develop a gap in the front teeth, which is normal and will generally close on its own.

If you would like more detailed information, talk to Dr. Byron Diehl about the palate expander. We can tell you what to expect from this treatment if we think it is best for your child’s unique needs, and how to make it as easy as possible for your child. Our goal is to provide your child with the healthiest teeth and bite possible, always making use of treatments that are both gentle and effective.

Tips for Cold and Flu Season

November 5th, 2025

It’s peak cold and flu season, a time to be especially conscious about your health. We have some suggestions to help you navigate this contagious time of year, with bonus tips for a healthy smile.

  • Wash Up! 

Bacteria and viruses can live for hours and even days on non-porous surfaces like doorknobs, phones, and keyboards. That’s why it’s so important to wash your hands before touching your mouth, nose, and eyes, before brushing and flossing, and before you cook or eat. Washing with plain soap and water will eliminate most germs.

Bonus Tip: Keeping your fingers away from your mouth does more than prevent the transmission of bacteria and viruses. Fingernail biting can damage brackets, wires, and even tooth enamel. Prolonged thumb or finger sucking can affect tooth and jaw alignment. Delicate gum tissue can be injured or infected by broken or dirty nails. If you’d like to break harmful oral habits, talk to Dr. Byron Diehl for suggestions.

  • Stay Hydrated

Hydration supports healthy skin, helps regulate blood pressure and body temperature, and is vital for digestion and other bodily functions. Proper hydration is also important for a healthy immune system and healthy mucous membranes, which will help you fight off colds and flu. Talk to your doctor about your ideal amount of daily hydration, whether from water, other fluids, or water-rich foods.

Bonus Tip: We also need to be hydrated to produce healthy levels of saliva. Saliva washes away food particles and bacteria from teeth and braces and helps neutralize enamel-eroding acidity in the mouth.

  • Eat Healthy Foods

A healthy diet is crucial for a healthy immune system, with foods such as lean proteins, fruits, vegetables, whole grains, and low-fat dairy products.

Bonus Tip: A balanced diet is good for your oral health, too! We need vitamins A and C for healthy gums and oral tissues, minerals like calcium and phosphorus to keep tooth enamel strong, and dairy products enriched with vitamin D, which enables our bodies to absorb the calcium we get in our diet.

What happens if you become ill despite your precautions? 

  • Reduce the Chance of Infecting Others

If you’re ill, you can help stop the spread of germs by limiting contact with other people, covering your mouth and nose when you cough or sneeze, washing your hands frequently, and cleaning the common surfaces in your house which harbor germs. 

Bonus Tip: Sharing isn’t caring when it comes to colds and flu. No matter how close you are to your family members or roommates, your toothbrushes shouldn’t be close at all. Let your brush air-dry in an upright position away from other brushes to avoid contamination. 

  • Be Choosy about OTC Medications 

If you take sugary cough or cold medications, brush or rinse afterward. Sugar-free cough drops are better for your teeth than sweet lozenges which bathe your enamel in sugar as you let them dissolve. 

Bonus Tip: Don’t bite into cough drops! You risk not only broken brackets and wires, but chipped and cracked teeth.

  • Keep Up with Healthy Habits

Be sure to keep hydrated, especially if you’ve been suffering from vomiting or diarrhea. Get the sleep you need to recover. Eat a well-balanced diet.

Bonus Tip: Stay on top of your dental hygiene and brush and floss as usual, with one caution. Vomiting brings up harsh stomach acids which weaken the mineral bonds keeping tooth enamel strong, so brushing right away can be abrasive. If you throw up, 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 with proper care, which includes getting the rest you need to recover. And you won’t be sharing germs with the people around you.

Bonus Tip: If you have an appointment scheduled with your orthodontist, reschedule if necessary. Your orthodontic team at Diehl Orthodontics will be happy to accommodate you to prevent the spread of germs and to make any procedure a more comfortable one.

It’s the height of cold and flu season in Redlands, CA, but you’re not alone! Talk to your doctor about immunizations and other preventative measures. If you do become ill, follow your physician’s recommendations. And if you have any orthodontic concerns, your orthodontic team is prepared with timely advice—at any time of year.

Halloween: Candy, costumes, and more!

October 29th, 2025

All Hallows' Eve, more commonly known as Halloween, is a yearly event celebrated on October 31, and one that is anticipated by the young and young at heart all over the world. Some scholars claim that Halloween originated from Celtic festivals that honored the dead or that celebrated the harvest, while others doubt that there's any connection at all to Samhain (a Gaelic harvest festival.) Regardless of its origin, our team at the orthodontic office of Dr. Byron Diehl hopes that Halloween is fun and enjoyed by all of our awesome patients!

Trick or treat?

In North America, Halloween is predominantly celebrated by children who dress up in costumes, which range from scary to cute, who then go around the neighborhood knocking on doors asking "trick or treat", and they are given candy in return. Trick-or-treating is a time honored tradition, and though many parents groan at the pounds and pounds of candy collected by youngsters and fear for the health of their teeth, there are a few things you can do to help their teeth stay in great shape until the candy is gone:

  • Limit the amount of candy they can consume each day
  • Have them brush their teeth after eating candy
  • Avoid hard, chewy candies as they can stick in hard to brush places
  • Keep candy out of sight to reduce temptation
  • Don't buy candy too far in advance to limit pre-Halloween consumption
  • Help or encourage your children to floss

Halloween Fun

Halloween isn't just about gorging on candy; there are other events associated with this festive day including carving jack-o'-lanterns, painting pumpkins, decorating sugar cookies, bobbing for apples, going to haunted houses, or just curling up on the couch with a bowl full of popcorn and watching some classic, scary movies.

Halloween Around the World

Some countries, like Australia, frown upon Halloween, claiming it is an American event and not based in Australian culture, while others like Italy have embraced the fun and celebrate much as Canadians and Americans do. Mexicans have been celebrating this fun day since around 1960, and it marks the beginning of the Day of the Dead festival. Some countries in Europe have come late to the party, but since the 1990s, countries like Sweden, Norway, and Germany have started celebrating Halloween as well, and finding children in costumes or having ghosts hanging in windows has become commonplace.

Halloween is about fun; stepping outside our normal lives and donning a costume or gathering with friends to knock on doors and ask for candy is as much a part of our culture as hot dogs and barbecue on Labor Day. Have a safe and happy Halloween from the team at Diehl Orthodontics!

Make Your Braces Bands Work for You!

October 22nd, 2025

Well, of course, they already are working for you—as an essential part of the alignment process. Rubber bands, also known as elastic ligatures, are used to secure the wires inside your brackets. But bands can be more than functional. Since the ligatures around each bracket are replaced when you visit our office, why not use that opportunity to choose a new color scheme as well?

  • Make a Statement

Bands offer a chance to coordinate your braces to an interest, team, or event. Are you a swimmer? Maybe cool blues and turquoises appeal to you. Batman forever? Black and yellow. (That will work for beekeepers, too.) Have a favorite sports team? Choosing team colors will support your team with every smile. Love your school? Show your spirit by wearing bands in your school colors. Favorite time of year? Celebrate by selecting festive bands in holiday colors.

  • Suit Your Mood

Fiery reds and oranges, tranquil blues and greens, millennial purples and pinks, or exuberant neon—you know that there are just some colors that suit your personality. Showcase that personality with your choice of band color. And if your mood changes, choose shades that express a completely different side of you.

  • Coordinate Your Colors

Match your bands to your eye color, your makeup, or the clothing colors you choose most often. If there’s a color profile that works for you, make your bands a part of it. If you don’t want everything matching, complement your coloring or clothing with a different but coordinating shade for a cohesive effect.

  • Keep a Low Profile

Most adults will stick with a monochromatic set of bands, and this might be a look that appeals to you as well. Grey and silver bands will blend nicely with silver braces. If you have clear or white brackets, you might want to test out which bands will be least noticeable. Clear bands can become discolored, and white bands can make teeth look darker. If there’s a band which mimics your own tooth color, this will be the choice for you.

  • Make Color Theory Work for You

Certain colors and tints bring out the best in your tooth color and work with your skin tones. White and yellow bands might make teeth appear duller, and any shade combination that resembles food particles (greens, browns, and black) is probably not a look you’re going for. Have fun with a color wheel and decide which colors you find most flattering.

Make your bands more than a tool—make them an accessory. There are so many colorful options available that you are bound to happen on a color scheme that just suits you. And if you change your mind? Change it up during your next visit to our Redlands, CA office!
