Why Dental Implants Sometimes Fail & How to Prevent It

If you have missing teeth, your dentist may recommend dental implants to restore your smile. Although dental implants are extremely reliable, they do occasionally fail. Fortunately, there are steps you can take to reduce the chances that you will experience any issues with your implants. Here is what you need to know about the most common causes of dental implant failures and how you can prevent them.


Infections are frequently the culprit when dental implants fail. An oral infection can make the gums swell and cause the jawbone that is supporting an implant to become weakened. When this happens, the implant may fail. The best strategy for preventing infections is to avoid smoking, which can impede blood flow to your gums, allowing infections to fester. Good oral hygiene can also help reduce the risk of infections, as can managing medical conditions that impact your oral health, such as diabetes.

Allergic Reactions

Although allergic reactions to dental implants are not common, they do occur. When patients are allergic to the titanium that make up the posts of dental implants, failure will often occur. Your dentist may recommend a titanium allergy test before you get your implants if he or she thinks you could be at risk of having a reaction.

Osseointegration Problems

Osseointegration is the process through which the post of the implant fuses with the bone in your jaw. When osseointegration is successful, the post will act like a tooth root, and the implant will stay firmly in place. If osseointegration fails, your implant may fail as well. Avoiding activities that can cause jaw injuries, not smoking, and following your dentist’s instructions while osseointegration takes place will reduce the risk of failure.

Everything You Should Know About Fluoride Supplementation

Fluoride has long been recognized as an important building block for healthy teeth. Despite some controversy, fluoride has been proven to be safe and effective when delivered in the right doses. Many people do not get an adequate amount of fluoride, which can leave them vulnerable to dental health issues. For kids, dentists often recommend fluoride supplements to protect their teeth from cavities, and in some cases, adults can benefit as well. Here are the facts you need to know about fluoride supplementation and its impact on your oral health.

Fluoride is added to many municipal water supplies.

Fluoride has long been added to many municipal water supplies to reduce the risk of cavities in the community. The level of fluoride added to water is recognized as safe and effective and is closely monitored. By drinking water with added fluoride, not only do you bathe your teeth with fluoride but you also get systemic fluoride, which helps tooth structures and increases fluoride in the saliva to protect the teeth.

Bottled and filtered water has reduced fluoride consumption.

As people turn away from tap water to bottled water or filtered water, they are reducing the amount of fluoride they get. Even when these water sources do have fluoride, they do not have optimum levels for dental health. Lack of fluoride can increase the risk of cavities and make teeth weaker.

Fluoride supplements can help reverse low fluoride levels.

There are many ways to increase fluoride intake. You can apply fluoride to your teeth topically with toothpastes and rinses. Your dentist can offer professional-grade, topical fluoride treatments. If you are considering increasing your child’s fluoride intake, consult your dentist first. Kids who get too much fluoride can develop fluorosis, a condition that causes striations or pitting on the teeth.

Know the Signs of Oral Cancer

Oral cancer is usually very treatable in its early stages, but many cases are diagnosed when they are more advanced because people don’t recognize the signs. When you get a dental checkup, your dentist will examine your mouth for signs of oral cancer, but between appointments, you should be mindful of potential symptoms that need to be evaluated. Consider making an appointment with your dentist if you notice any of these symptoms.

Mouth Sores That Won’t Heal

Almost everyone gets mouth sores from time to time, and in most cases, they are not serious. However, if a mouth sore won’t go away, you should have your dentist examine it. Call your dentist about any mouth sore that lasts for more than two weeks to see if it should be biopsied. The same is true of other lesions that develop in the mouth, including patches of thick skin, lumps, or swelling.

Mouth Pain

Pain is a common symptom of oral cancer. In some cases, pain will be limited to a specific location of the mouth. In other instances, you may experience an all-over sensation of discomfort and aching throughout your mouth. Your dentist should evaluate persistent tooth or jaw pain. A sore throat that won’t go away can also indicate oral cancer. Instead of throat pain, some people with oral cancer feel like something is caught in their throat that won’t go away or that interferes with swallowing.

Loose Teeth or Dentures

Oral cancer can cause gums to swell, which in turn can make teeth and dentures become loose. Gum disease can also cause this symptom, so it’s important to see your dentist to get an accurate diagnosis and the necessary treatment.

Common Problems with CPAP Therapy

Although CPAP therapy is effective for some people suffering from sleep apnea, many others cannot adapt to treatment and experience even more sleep problems than before they had their CPAPs. In these cases, your dentist could have the solution to your disrupted sleep. Oral appliance therapy is an alternative to CPAP therapy for sleep apnea. It often solves many problems associated with CPAP treatment, allowing sufferers to finally get the rest they need. Here is a closer look at some of the issues people have with CPAPs that can be reversed with oral appliance therapy.

Trouble Sleeping While Wearing the Mask

There is no getting around the fact that undergoing CPAP therapy means sleeping with a mask on your face. The mask is also attached to a hose, which is attached to a machine. Learning to sleep this way can take a huge adjustment, and some people never get used to it at all. Experiencing fitful sleep because you’re uncomfortable in the mask makes CPAP therapy pointless. Oral appliance therapy doesn’t involve a mask, which makes it much more comfortable for many people.

Skin Irritation

CPAP masks are notorious for causing skin irritation. The straps can rub against your skin while you’re sleeping, while the part of the mask that goes across the bridge of your nose can cause pain and pressure. Some people develop mild irritation, while others may develop skin sores. Oral appliances stay in your mouth, so they don’t cause these issues.

Difficulty with Forced Air

CPAPs keep your airway open with forced air. Some people are uncomfortable with the forced air and feel like they can’t breathe. With an oral appliance, your jaw is gently shifted forward, allowing you to breathe without the need for forced air.


Don’t let sleep apnea affect your rest for another night. Make an appointment with John Carson, DDS to see if you are a candidate for oral appliance therapy. To contact our dentist in Tucson, call (520) 514-7203.
