How does whitening toothpaste work and how effective it is at whitening teeth?
April 25th, 2017

Brushing your teeth twice a day with fluoride toothpaste that has the American Dental Association seal of approval can help prevent tooth decay and relieve other conditions, such as bad breath, sensitive teeth, and gingivitis.
Beyond these health effects, another motivation for frequently brushing your teeth with high-quality toothpaste is to keep your teeth white. If you want whiter teeth but do not want to undergo in-office or at-home bleaching treatments, you might consider choosing whitening toothpaste for your daily brushing.
Why Consider Whitening Toothpaste
Whiter teeth are more attractive, which can help you feel more confident in your smile. Your smile is also one of the main components of the first impression you make on people in your professional and personal life. 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
The American Dental Association explains that all toothpaste has whitening properties because they help remove food particles from your teeth. To carry the American Dental Association seal for whitening, however, 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, some 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 can sometimes respond, and yellowish teeth are most likely to become pearly white with bleaching.
If Dr. Rick Johns 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.
Hypersensitive Teeth
April 18th, 2017

It is common to experience dentine hypersensitivity, with symptoms ranging from moderate to severe. Why does it happen and how do you know if this sensitivity is something to be concerned about? The first step is to determine the cause.
The most common cause of the sensitivity is exposure of the dentin. Dentin is the layer immediately surrounding the nerve of the tooth. It is alive and usually covered by the gum tissue. When gum recession is present hypersensitivity is common. Other contributors to temporary tooth hypersensitivity include teeth whitening and dental procedures such as fillings, periodontal treatment, and braces placement or adjustment. These are temporary and should be of no concern.
Permanent hypersensitivity, however, may require treatment. To understand the cause of sustained hypersensitivity, let us explain the structure of dentin and why it serves as a ‘hot spot’.
The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When dentin tubes are exposed, there is a direct connection between the mouth and dental pulp, which houses the nerve and blood supply of the tooth. External stimuli, such as mechanical pressure (tooth grinding or clenching - bruising the ligaments holding the teeth in place), temperature changes, as well as chemical stimuli (sweet–sour) are transmitted to the pain-sensitive dental pulp and activate nerve endings. A short and sharp pain is the result. These external stimuli cause fluid movement in the open tube that is transmitted as pain sensations. Something needs to be placed into the dentin tube to plug it and stop this fluid movement.
The first step in doing something about dental hypersensitivity is to determine the cause; our professional team at Rick Johns Dental can help you with this. Whether the sensitivity is due to exposed dentin or an underlying cause such as abscess or decay, corrective measures are needed. Contact us sooner rather than later so Dr. Rick Johns can reduce the sensitivity, and provide you with some relief!
Is sleep apnea linked to cancer? Studies say, ‘Yes’.
April 11th, 2017

Recently, multiple studies have concluded that people with sleep apnea, a disorder that causes snoring, fatigue, and dangerous gaps in breathing at night due to throat muscles collapsing, are five times more likely to develop cancer. In fact, one of the studies found that people with the most severe forms of sleep apnea had a 65 percent greater risk of developing cancer of any kind.
Researchers believe this could be due to the body lacking enough oxygen, a condition known as hypoxemia. When people are deprived of oxygen, their bodies react by producing more blood vessels, which can feed cancer cells, and as a result cause tumors to grow and spread.
Approximately 28 million North Americans suffer from sleep apnea, with many cases going undiagnosed. This is due to most cancer patients not mentioning any sleep problems they experience unless their physician asks them.
Patients at Rick Johns Dental who suffer from sleep apnea can be treated using continuous positive airway pressure (CPAP) therapy, which produces a stream of air to keep the upper airways open while you sleep. An oral appliance may be another option if CPAP therapy isn’t an option. If you have sleep apnea, Dr. Rick Johns and our team will help you understand all of your treatment options, finding one that suits your needs.
If you think you may have sleep apnea, please give us a call at our Highland, IN office to schedule an appointment.
What stinks?
April 4th, 2017

Spilling soda on someone’s white shirt, telling an off-color joke at an inappropriate time, or sneezing chewed food all over the dinner table all pale in comparison to the socially unacceptable, embarrassing blunder of having ... bad breath!
Five Possible Causes of Halitosis
- Poor oral hygiene practices. Failing to brush your teeth encourages anaerobic bacteria growth, which involves a type of bacteria that emits volatile sulfur compounds (gases) responsible for smelly breath.
- If you have tonsils, you may have tonsil stones embedded in the fissures of your tonsils. Tonsil stones are hard, tiny pieces of bacteria, dead oral tissue, and mucus that form inside tonsil crevices. When accidentally chewed, they release extremely foul odors that others can smell and you can actually taste.
- You have a chronically dry mouth due to medications, allergies, or persistent sinus conditions that force you to breathe through your mouth. Anaerobic bacteria thrive in dry, stagnant environments where oxygen content is minimal. Consequently, a dry mouth tends to lead to smelly breath.
- You have acid indigestion or GERD (gastroesophageal reflux disease). If you constantly belch stomach gases, this not only causes your breath to smell fetid but it can lead to enamel erosion and tooth decay.
- You have one or more oral diseases: gingivitis, periodontitis, or infections in the gums known as abscesses.
Improving oral hygiene practices may eliminate bad breath, but if brushing, flossing, and rinsing with a fluoride mouthwash twice a day doesn’t stop people from backing away from you when you open your mouth, it’s time to visit Rick Johns Dental.
