What is biofilm?

December 17th, 2014

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, Dr. Keldsen , 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.

Is it possible to over brush?

December 10th, 2014

Our team at Keldsen Family Dental Care will tell you brushing on a regular basis is critical for a healthy mouth, but you can definitely overdo a good thing. Known as “toothbrush abrasion,” over brushing can lead to sensitive teeth and receding gums, not to mention the wearing down of the protective layers of your tooth enamel. Over brushing can also push back your gums, and in the process, expose the dentin layer under the enamel.

“So, how do I avoid over brushing?”

  • Use a soft or extra-soft bristled toothbrush to prevent gum damage and wear on the soft tooth dentin
  • Keep in mind which direction bristles face when you brush. They should be perpendicular, not parallel. Place the head of your toothbrush with the tips of the bristles at a 45-degree angle to the gum line and brush away!
  • Move the toothbrush with short strokes and a scrubbing motion, several times in each spot – don’t saw back and forth across the teeth with your toothbrush.
  • Apply just enough pressure to feel the bristles against the gums. If you are squashing the bristles, you're brushing too hard.
  • Replace your toothbrush when you notice frayed and bent bristles.
  • Brush for two minutes at a time

Teeth Grinding

December 3rd, 2014

If you are waking up with jaw pain, tension headaches, or facial pain, you may be suffering from a condition known as bruxism. This means you could be grinding or clenching your teeth while you sleep. Some people aren’t even aware they are grinding or clenching their teeth at night, until a visit to us reveals significant tooth enamel loss. Fortunately, there is a non-invasive and effective solution for teeth grinding, and the tooth enamel damage it can cause, in custom-fabricated nightguards.

Causes of teeth grinding

Tension, stress, and anxiety experienced during the daytime can carry over to an individual’s sleep, and lead the person to grind his or her teeth together or clench the teeth unknowingly. Sleep apnea is another condition that can result in bruxism. Regardless of the cause, however, frequent clenching and teeth grinding wears down the chewing surfaces of the teeth, reduces tooth enamel, and can result in a cracked or chipped tooth, crown, or filling.

Nightguards for teeth grinding

Custom nightguards are fabricated to fit like a glove and protect your teeth from the adverse effects of bruxism. Nightguards are created through a non-invasive process that simply takes an impression of the bottom and top rows of teeth. The result is a nightguard that is flexible, comfortable, and personalized to your mouth.

Benefits of nightguards

Nightguards are helpful to reduce or eliminate the symptoms of dental damage incurred as a result of teeth grinding. They can reduce the discomfort associated with a sore jaw, headaches, tooth sensitivity, ear pain, and facial pain that many patients experience as a result of clenching or grinding of their teeth. In severe cases of bruxism, patients can develop loss of hearing, jawbone misalignment, and TMJ. Therefore, customized nightguards can help prevent the progression of teeth grinding into these more serious conditions.

At-home tips to reduce or prevent teeth grinding

Although it’s important to wear your nightguard faithfully if you grind your teeth at night, you can follow a few self-care tips to help to prevent your teeth grinding from worsening.

  • Reduce tension and stress. Whether you take a warm bath before bed, listen to soothing music, or exercise, practice stress-relieving activities to wash away the tensions of the day.
  • Avoid alcohol. In some patients, alcohol increases teeth grinding tendencies.
  • Avoid caffeine. In some individuals, caffeine increases the likelihood of teeth grinding.
  • Focus on relaxing jaw muscles. Make a conscious effort to keep your jaw relaxed. A warm washcloth against your cheek, sticking your tongue between your teeth, and avoiding chewing pencils, pens, and gum are all ways to train the muscles of your jaw to stay relaxed.

If you suspect you may be grinding your teeth at night, visit Dr. Keldsen and our team at Keldsen Family Dental Care for an evaluation at our convenient Bend, OR office.

Thanksgiving

November 26th, 2014

At Keldsen Family Dental Care, we love to celebrate the holidays with vigor! Dr. Keldsen would love to share some unique ways of celebrating Thanksgiving from beyond the Bend, OR area to the national level!

When Americans sit down to dinner on the last Thursday of November, the day that Abraham Lincoln designated as the day on which Thanksgiving would be celebrated, they do so thinking that the first Thanksgiving feast was held at Plymouth in 1621. According to National Geographic, the Spanish explorer Francisco Vásquez Coronado and his men celebrated a feast of Thanksgiving in Texas in 1541, giving Texas the distinction of being the first place where Thanksgiving was celebrated.

Different Types of Celebrations

Native Americans had rituals around which they celebrated in hopes of ensuring a bountiful harvest. The Cherokees had a Green Corn Dance that they did for this very purpose. The Pilgrims (not to be confused with the Puritans,) rejected any type of public religious display. They held a three-day long non-religious Thanksgiving feast. Although they said grace, the focus of their celebration was on feasting, drinking alcohol (they did have beer,) and playing games.

The Pilgrims at the Plymouth Plantation celebrated a different day of Thanksgiving in 1623. Plagued by a crop-destroying drought, the settlers prayed for relief. They even fasted. A few days later, they got the rain they so desperately needed. Soon thereafter, they received another blessing when Captain Miles Standish came with staples they couldn't otherwise get. He also told them that a Dutch supply ship was en route. In gratitude for the abundance of good fortune, the Plymouth settlers celebrated a day of prayer and Thanksgiving on June 30, 1623.

The Story of Squanto

No discussion of Thanksgiving is complete without a discussion of Squanto, or Tisquantum, as he was known among his people, the Patuxet Indians. It is believed that he was born sometime around 1580. As he returned to his village after a long journey, he and several other Native Americans were kidnapped by Jamestown colonist, Thomas Hunt. Hunt put them on a ship heading to Spain where they were to be sold into slavery.

As fate would have it, some local friars rescued him and many of the other kidnapped natives. Squanto was educated by the friars. Eventually, after asking for freedom so he could return to North America, he ended up in London where he spent time working as a ship builder. By 1619, he was finally able to get passage on a ship headed to New England with other Pilgrims.

Upon arriving at Plymouth Rock, he learned that his entire tribe was wiped out by diseases that accompanied earlier settlers from Europe. In gratitude for passage on their ship, he helped them set up a settlement on the very land where his people once lived. They called the settlement Plymouth. Since they knew nothing about how to survive, let alone how to find food, Squanto taught them everything, from how to plant corn and other crops, how to fertilize them, how and where to get fish and eels and much more.

After a devastating winter during which many settlers died, thanks to Squanto's teaching, they had an abundant harvest. After that harvest, they honored him with a feast. It is this feast of 1621 which was celebrated between the Pilgrims and Wampanoag Indians that is widely considered the first Thanksgiving celebration.

About the Meal of the Plymouth Settlers

Surviving journals of Edward Winslow that are housed at Plymouth Plantation indicate that the first Thanksgiving feast was nothing like what Americans eat today. The meal consisted of venison, various types of wild fowl (including wild turkey,) and Indian corn. There were no cranberries, stuffing, pumpkin pie, potatoes, or any of the other “traditional” foods that appear on modern menus.

Today, Thanksgiving is celebrated on the fourth Thursday of November, the day that Abraham Lincoln designated as the holiday. It is still a day of feasting, and for some, a day of prayer and thanksgiving. For others, it is a celebration of gathering, especially for families. Still others may celebrate in entirely different ways, including watching college football bowl games, or by playing family games.

If you ever wonder why you're so tired after the Thanksgiving meal, it's because turkey contains an amino acid, tryptophan, and it sets off chemicals whose chain reaction combine to make people sleepy.
