How effective is whitening toothpaste?

July 16th, 2025

The American Dental Association encourages you to brush your teeth twice a day with fluoride toothpaste to prevent dental problems such as tooth decay, bad breath, sensitive teeth, and gingivitis.

Beyond these health effects, frequent brushing of your teeth with a high-quality toothpaste can keep your teeth white. If you desire a whiter smile without in-office bleaching at our Aspen office, use of a whitening toothpaste is a great option for you.

Why Consider Whitening Toothpaste

Whiter teeth are more attractive and can help you feel confident in your smile. Having a whiter smile and greater self-assurance can send the message that you take care of yourself and are confident in your abilities.

How Whitening Toothpaste Works

Although every toothpaste has whitening properties because they all help to remove food particles from your teeth, the American Dental Association says whitening toothpaste must contain certain chemicals that help remove stains.

Unlike bleaching products, which contain carbamide peroxide or hydrogen peroxide, whitening toothpaste only cleans the enamel rather than changing the color of your teeth. To obtain the benefits of whitening toothpaste, you need to use it regularly.

The Effectiveness of Whitening Toothpaste Varies

Due to individual variations in the color of your teeth, certain people are more likely than others to achieve the desired results with whitening. Teeth that are tinted grayish are unlikely to respond well to bleaching, while brown teeth may sometimes respond, and yellowish teeth are most likely to become pearly white in response to bleaching.

If Dr. Robert Christensen and our staff believe that bleaching is not a viable option for you, proper oral hygiene and the use of a whitening toothpaste are your best bets for keeping your teeth as white as possible. In addition, avoid using tobacco products, and rinse your mouth after drinking coffee.

Is Charcoal Teeth Whitening Safe?

July 9th, 2025

Health and beauty trends surface on the web every day, and it can be difficult to tell which ones are worth your time, or even safe, for that matter. Perhaps one of the biggest dental trends recently on Facebook, YouTube, and Instagram has been teeth whitening through brushing with activated charcoal.

Unfortunately, charcoal whitening isn’t everything the Internet makes it out to be. Activated charcoal isn’t what you use to grill at a summer barbecue; it’s an oxidized substance made from peat, coal, wood, coconut shell or petroleum heated with a gas.

Toxins and surface stains can cling to charcoal due to its adhesive qualities, which is why some people declare it’s perfect for removing discoloration on teeth. Although it may show quick results initially, charcoal is nothing more than a temporary solution.

The abrasive texture may roughen up enamel, which will make it easier for future stains to stick to the surface of your teeth. They may show stains shortly after you use charcoal on them, and may become even more discolored than before.

It’s crucial to emphasize the results of damaged tooth enamel because it cannot replenish itself, which means any damage is permanent. People with receding gums or sensitive teeth especially should steer clear of charcoal because it can make brushing too harsh and worsen sensitivity.

Long-time use can deplete enamel, which over time exposes dentin: the soft, yellowish layer in the tooth. This puts you at a higher risk for cavities, tooth discoloration, and complicated dental problems such as periodontal disease in the future.

The American Dental Association does not approve of charcoal as a safe means for whitening teeth. If you do choose to use it, do so with caution.

Charcoal should be used once every other week at the most, even if your teeth feel fine. The only proven ways to whiten teeth safely are with ADA-approved whitening products or in-office bleaching treatments overseen by a dental professional.

Before you begin any whitening treatment at home, consult with Dr. Robert Christensen to make sure your teeth won’t be harmed in the process. If you are already experiencing sensitivity, stop charcoal use immediately and make an appointment with our office right away.

Happy Fourth of July!

July 2nd, 2025

Happy Independence Day from Dr. Robert Christensen and team! The Fourth of July celebrations in America may have changed a lot over the years, but there is no doubt that we Americans love to celebrate the anniversary of our country's independence! Today we're devoting the Robert M. Christensen, DDS, PC blog to some fun facts about the Fourth!

  • My, how we have grown! This year the United States Census Bureau estimates that our country has 313.9 million residents celebrating the Fourth of July this year, but back in 1776 there were just 2.5 million members of the country.
  • Our country loves to show how proud that we are of our independence. Did you know that there are 31 United States places with the word “Liberty” in their names? The state of Iowa actually has four towns with the word Liberty in the name: Libertyville, New Liberty, North Liberty, and West Liberty.
  • The United States loves Fourth of July food! It is expected that around 150 million hot dogs are eaten on the Fourth each year. One of the Fourth's most popular sides, potato salad, goes just perfectly with the hotdogs and hamburgers that are standard Fourth of July fare. Some people choose potato chips instead, but we wouldn't have such a plethora of potatoes if not for the prodigious production of the states of Idaho and Washington -- they provide about half of all the potatoes in the United States today!
  • Americans love celebrating the Fourth outdoors: About 74 million Americans fire up their BBQ grill every Fourth of July.
  • The Chinese contribution: Did you know that Americans have spent more than $211 million on fireworks that were imported from China?

No matter how your family chooses to celebrate the Fourth, stay safe, take precautions, and don't forget to brush after your fabulous Fourth feast!

Sleep Apnea and Snoring

June 25th, 2025

Snoring may not be something you take seriously. You might even laugh or joke about it. But the fact is, anytime you or your partner snore to the point of waking, it could be a sign of serious health problems.

Sleep Apnea and Its Effects

Sleep apnea is a sleep disorder that is potentially dangerous, and the most common symptom is loud snoring. Breathing repeatedly starts and stops throughout the night, and you wake up feeling tired. Other serious effects from sleep apnea could be potentially dangerous to your health if left unaddressed.

Besides losing a good night's sleep, you may experience difficulty concentrating. Depression, risk of heart attack, irritability, high blood pressure, memory loss, sexual dysfunction, and chances of stroke all increase when sleep apnea is not treated.

Sleep apnea occurs when the muscles in the back of the throat relax to the point of inhibiting natural breathing. The muscles used to support the soft palate relax and the airway closes, causing breathing to stop for ten to 20 seconds. This lowers the oxygen level in the brain. As the brain senses the inhibited oxygen levels it rouses the sleeper awake so the airway can reopen. Normally, the reawakening is so brief the person won't remember it.

If you think you may have sleep apnea, visit our Aspen office and let Dr. Robert Christensen determine what treatment is needed. Without it, you could risk losing more than a restful night's sleep.

Prevention and Treatment

Anyone can develop sleep apnea, but it is more common among middle-aged adults who are overweight. Dr. Robert Christensen can help you determine the cause and suggest positive treatment.

A common treatment for apnea is the placement of oral devices that are designed to help keep the airway open. By bringing the jaw forward, the device opens the airway and thereby discourages snoring. We are experienced in sleep apnea appliances, and Dr. Robert Christensen can prescribe a fitted device and monitor its success with follow-up therapy.

A continuous positive airway pressure mask, known as a CPAP, is among the other treatment options. A mask is fitted over the mouth and forces oxygen through the throat while you sleep. The pressure holds the soft tissue and throat muscles open.

Our professionals at Robert M. Christensen, DDS, PC can advise you of other ways to prevent sleep apnea, including weight loss, avoiding alcohol, or alternative sleeping positions. We can help you sleep return to easy sleep, knowing you are safer and healthier during your resting hours.
