What are Sealants?

November 15th, 2017

Sealants offer many benefits, but the best is their ability to protect your molars. Molars are full of small caverns that can be the perfect breeding ground for tooth decay and plaque buildup.

Use of protective sealants prevents this buildup from happening. Although children often receive sealants for routine preventive care, they aren’t the only ones who can benefit from this treatment. Sealants can also help adults who have deep canyons or grooves in their teeth.

They are commonly placed on the rear molars that tend to suffer the most decay. Because your molars are used substantially as grinding surfaces, food is more likely to be trapped among them.

Sealant solution consists a composite material that contains bonding agents that seal the top of your teeth. The process is quick and painless, which makes it a great solution for both children and adults who have had trouble with cavities and tooth decay. Sealants also last for several years, and repair is a simple process that can be completed by Dr. Keldsen.

The process of putting sealants on teeth starts with the tooth getting cleaned. We clean it with a type of baking soda spray called sodium bicarbonate. Then acid is etched onto the teeth to rough up the surface.

We apply an alcohol-based liquid to dry the area where the sealant is supposed to go. After it completely covers the surface of the treated teeth, the sealant is cured with a light that makes it hard and long-lasting.

Getting sealants can prevent the possible restorative costs that come from cavities. Sealants help to protect your tooth’s enamel from harmful acids and prevent decay, which can be an investment in itself. The whole process is quick, so it should be easy to schedule an appointment at Keldsen Family Dental Care.

Famous Dentists in History

November 8th, 2017

Every six months or so you head down to your local dentist for a teeth cleaning, but have you ever thought that your dentist could one day be famous? Well, the chances are unlikely, however, there have been a number of dentists throughout history that have achieved acclaim and celebrity coming from a profession that is not typically associated with such regard. Here are a few examples:

Doc Holliday

Perhaps most famous for his gun fight at the O.K Corral alongside his buddy, Wyatt Earp, but "Doc" also had a day job as a dentist. He was trained in Pennsylvania and later opened a thriving practice near Atlanta. Sadly, Holliday came down with a case of tuberculosis and had to close his practice. He then packed his stuff and moved west, and we all know how the rest of the story goes.

Mark Spitz

Known around the world as a champion swimmer, Spitz was actually accepted into dentistry school before he became an Olympic gold medalist. While he ultimately decided not to attend school, it's safe to say he made the right choice considering he now has seven gold medals.

Paul Revere

The most famous dentist to come out of the American Revolution, Paul Revere was a man of many hats. He, of course, is known throughout history books for warning the colonies of the impending British troops on the attack, but when he wasn't involved in the fight he had a few different jobs. He was a silversmith, but also advertised his services as a dentist. More specifically, he specialized in making false teeth for people in need.

Miles Davis' Father

Miles Davis Jr. was one of the most acclaimed and influential jazz musicians of all time and his dad was a dentist. Miles Davis Sr. had a thriving dental practice and was a member of the NAACP. Dentistry was how he paid the bills and provided for Miles Jr., so in some ways it seems we all have the dental profession to thank for allowing Miles Jr. to become such a fantastic musician, and treating us to his jazz stylings.

Dr. Keldsen may not be famous, but you’ll still receive excellent care each and every time you visit our Bend, OR office.

Ease up on your gums — don’t brush your teeth too hard!

November 1st, 2017

A lot of patients go at their teeth like they were sanding an old floor—that is to say, way too hard! Brushing too hard is probably the most common mistake patients make in their oral care routine, and it can be detrimental to the gums and teeth.

What can brushing too hard cause?

  • Receding gums
  • Bone loss around teeth
  • Loss of teeth
  • Tooth sensitivity, especially to hot and cold
  • Worn down enamel

Brushing too hard wears away at your gums, which can lead to the neck of the teeth being exposed. This part of the tooth isn't covered by hard enamel like the rest of the tooth and hence the soft inner layer, or dentin, is exposed. Dentin is very sensitive to hot and cold and much more susceptible to bacterial decay. Once the gums recede due to improper brushing, it’s usually irreversible.

How to brush your teeth properly

You know you're supposed to brush your teeth twice a day, so why not do it right? First and foremost, you should only ever brush with a soft bristled brush—not medium or hard—unless directed otherwise by Dr. Keldsen. Unless you have braces or specific oral health issues, brushing twice a day for two minutes is usually plenty.

The main purpose of brushing is to remove plaque from your teeth and gums. Plaque is actually soft and is a buildup of bacteria, saliva, and food debris. You really don't need to brush hard to remove it, just make sure you aim your toothbrush at the gum line (where plaque grows) and brush in small circular motions, never a back-and-forth motion.

It's also wise to hold your toothbrush gently. People tend to brush harder the tighter they hold their toothbrush.

Still have questions about proper tooth brushing technique or gum health? Ask any staff member or Dr. Keldsen during your next visit to our Bend, OR office; we'd be happy to help!

Zirconia Dental Implants

October 25th, 2017

Since dental implants first started being implemented in the 1980s, they have been primarily made of titanium. Recent advances in implant technology have allowed dental implant manufacturers to shift from all-metal implants, to part-metal and part-ceramic implants, to the newer all-ceramic or zirconia implants.

Zirconia implants are made of high-impact resistant ceramic called tetragonal zirconia polycrystal (ZrO2+Y2O3). They remedy many of the issues and complaints doctors and patients have with traditional metal implants and have several advantages—let’s take a look at some of them.

Advantages of Zirconia Implants

  • Do not cause allergic reactions – Although titanium is considered non-toxic, some people still have allergic reactions to titanium. Zirconia implants are inert, non-corrosive, and hypoallergenic.
  • Have been used for decades in medical applications – Millions of patients have had zirconia used safely and effectively as the base material for their hip replacements. The zirconia used for medical applications also undergoes strict radiation monitoring to ensure its safety for use within the body.
  • They are incredibly strong – Unlike titanium implants, zirconia offers a much higher degree of resistance to scratching, corrosion, and fracture. The aerospace industry even uses zirconia (ZrO2) due to its high resistance to heat and fracture. This all means a safer and more aesthetically pleasing result for the patient.
  • One-piece design is more hygienic – Zirconia implants are a one-piece design, meaning there is nowhere for bacteria to build up or liquids to penetrate like with titanium implants. They are highly biocompatible (how a material reacts with the human body) which leads to healthier gums and no risk of corrosion.
  • Implant margin is at gum not bone level – With titanium implants the margin (or gap between the implant and the tooth) is at bone level, which can lead to bacterial buildup since you can’t brush there. The zirconia implant margin, which is at gum level, allows you to brush and clean your implant and restoration regularly.

If you are in need of a restorative dental implant, it would be wise to consider zirconia due to its many advantages. It might not work in every situation, but feel free to discuss your options with Dr. Keldsen or one of our Bend, OR staff members.
