Your Step-by-Step Guide to the CEREC Process

Chairside Economical Restoration of Esthetic Ceramics, more commonly referred to by its acronym, CEREC, is a state-of-the-art milling machine and 3D software platform. It allows cosmetic dentists to create custom dental crowns while the patient waits. This means that it’s no longer necessary to send an impression away to a lab, and wait for weeks to receive the crown.

Oral Exam

The first step before any restoration treatment is to conduct a thorough oral examination. Your dentist will make sure that you can benefit from a dental crown. If your tooth is only chipped instead of severely fractured, it may only need a filling. Your dentist will discuss your treatment plan with you before taking any action.

Tooth Preparation

Once you’ve agreed to move forward with the dental crown, your dentist may apply a local numbing agent, if needed. He or she will then prepare your tooth to receive the CEREC crown. Usually, the tooth needs to have damaged or decayed matter removed.

Optical Impression

To make a dental crown in the traditional way, patients have to bite down on a tray filled with mold material. This isn’t needed with CEREC technology. Instead, your dentist applies a safe, tasteless powder to the tooth, and uses a specialized camera to take an optical impression.

Restoration Creation

The optical impression is processed with the CEREC 3D software. The software converts it into a 3D model, which your dentist will use to design your custom dental crown. The final 3D model is sent to the CEREC milling machine, which carves your new dental crown from a ceramic block. This whole process can be completed within about 20 minutes while you relax in the treatment chair. The result is a perfectly shaped, tooth-colored dental crown.

Crown Bonding

Once the ceramic crown is finished, the dentist will place it in your mouth. This is done without oral adhesive material, and is simply to verify the proper fit and bite. Then, after giving it a final polish, your dentist will bond it firmly in place.

What Your Dentist Wants You to Know About Smoking

Prior to the mid-1960s, smoking was widely thought of as a hip thing to do. Cigarette companies had built a loyal following by advertising their products as a way to improve health. Fortunately, everyone now knows that smoking kills, but overcoming this addiction is still a significant challenge. If you’re looking for more motivation to help you finally get cigarettes out of your life, just have a friendly chat with your dentist.

Smoking causes gum disease and tooth loss.

Smoking is one of the biggest risk factors of periodontal disease and tooth loss. Gum disease starts as gingivitis, which is the inflammation of the gum tissue. Over time, the gum tissue begins to pull away from the teeth. The infection can attack the supporting structures of the teeth, including the underlying bone. Eventually, tooth loss results.

Smoking causes oral cancer.

Smoking can cause cancer almost anywhere in the body, including in the mouth and throat. And since many smokers don’t see a dentist regularly for oral cancer screenings, the cancer can progress untreated until drastic surgery is needed. Permanent facial disfigurement and impaired oral function are the results.

Smoking turns your teeth yellowish-brown.

Tobacco use can turn your teeth yellow pretty quickly. And after years of smoking, the teeth can begin to turn brown. Many smokers are embarrassed about their teeth, and so they may try to avoid smiling and eating in public.

A smile makeover can restore your oral health when you quit smoking.

Don’t let smoking control your life any longer. Reward yourself for quitting with a smile makeover from your cosmetic dentist. Your smile makeover may include:

  • Gum disease treatment
  • Dental implants
  • Teeth whitening
  • Dental veneers
  • Porcelain crowns

Even if you’re still working on quitting, you should get an exam, professional cleaning, and oral cancer screening.

You’ll find warm, friendly professionals and a non-judgmental atmosphere at the dental office of John Carson, DDS. We know how hard it is to break an addiction to smoking, and we want to help you restore your beautiful, healthy smile. Call us today at (520) 514-7203 for preventive, restorative, and cosmetic dentistry care in Tucson, AZ.

Oral Complications in Patients with Celiac Disease

Oral health doesn’t exist in a vacuum. Oral health is affected by your overall health, and vice versa. Celiac disease is one of the systemic diseases that may lead to oral health complications. Patients with celiac disease are encouraged to see their dentist regularly, and to disclose any changes to their health history at each dental visit.

Dental Enamel Defects

Celiac disease can occur very early in life. Patients who are diagnosed with celiac disease earlier than seven years of age can be at a higher risk of enamel problems. These are caused by the disrupted formation of the enamel on the baby teeth and permanent teeth. Enamel defects can stem from nutritional deficiencies and an immune-mediated response. Some potential signs of enamel defects due to celiac disease include:

  • Horizontal lines or grooves
  • Rough surface
  • White or yellow opacities
  • Structural defects

Tooth Decay

Tooth decay is a common problem for patients of all ages, with or without celiac disease. But experts have suggested that dental caries occur with even greater frequency in children with celiac disease. This may be due to structural changes of the teeth, as well as nutritional deficiencies directly caused by the disease.

Canker Sores

Patients with celiac disease are more susceptible to aphthous ulcers, or canker sores, than non-celiac patients. These outbreaks can cause discomfort or pain while eating, talking, and brushing the teeth. Like celiac disease itself, these symptoms can be lessened by strictly adhering to a gluten-free diet.

Delayed Tooth Development

A child’s baby teeth generally start to fall out at around age six. But in children with celiac disease, the baby teeth can stick around longer than usual. Their permanent teeth may erupt later than usual too. This is because celiac disease can result in delayed dental and skeletal development.

Could Your Partner Have Sleep Apnea?

There’s nothing quite like sinking into a comfortable bed to get some much-needed shut-eye after a long day’s work. But then, your partner starts snoring, and you end up lying awake for hours. Could sleep apnea be to blame? Consider scheduling an appointment with the dentist to find out about oral appliance therapy that can effectively treat the symptoms of sleep apnea.


Plenty of people snore despite not having sleep apnea. But if your partner snores loudly and frequently, it’s worth getting it checked out. Treating sleep apnea with oral appliance therapy or CPAP therapy will put a stop to the snoring, and allow you and your partner to sleep better at night.

Gasping for Air

Snoring by itself doesn’t automatically indicate sleep apnea. Before reaching for the earplugs, pay attention to your partner’s breathing as he or she sleeps. People with sleep apnea periodically cease to breathe during sleep. They then briefly awaken, which may be accompanied by a gasping noise.

Waking up Frequently to Urinate

If you’re a light sleeper, you might be awakened when your partner gets out of bed. Provided he or she isn’t a sleepwalker, these nighttime wanderings are probably trips to the bathroom. People with sleep apnea tend to wake up more frequently to relieve themselves.

Waking up with a Headache

Have you noticed your partner rubbing his or her forehead while drinking a morning cup of coffee? Sleep apnea sufferers often have headaches upon waking up. It’s caused by lowered oxygen levels in the brain.

Being Diagnosed with Related Medical Conditions

Other potential indicators that your partner might have sleep apnea include being diagnosed with other medical conditions. People with the following issues are more likely to also have sleep apnea:

  • Overweight or obesity
  • High blood pressure
  • Insomnia

If you suspect your partner might have sleep apnea, you can encourage him or her to visit the Tucson dental practice of John Carson, DDS. We offer effective oral appliance therapy for sleep apnea, along with comprehensive radiology services. Call (520) 514-7203.
