What Are Dental Sealants?

September 30th, 2026

You’re constantly playing defense. Your child spends two minutes in the morning and two minutes at night carefully brushing and flossing with a fluoride toothpaste. You make sure sugary and acidic foods are not a major part of your diets. Your child visits our Maplewood & West Orange office for regular exams and cleanings. Really, how can a cavity get past all that?

But even with the best defensive practices, you don’t have a level playing field—literally. The tops of our molars and premolars don’t have the smooth, easy-to-clean surfaces that our other teeth have. If you look at the chewing surfaces, you will notice deep grooves which toothbrush bristles have a much harder time reaching.  

Plaque and food particles can become trapped in these grooves (known as pits and fissures), providing perfect conditions for a cavity to develop. That is why cavities are so common in newly erupted molars. Dental sealants protect these teeth from cavities by providing a barrier which smooths out the surface of the tooth and prevents food and bacteria from reaching the molar’s crevices.

Most sealants are invisible plastic resin coatings which we apply in our Maplewood & West Orange office. Usually the procedure is so quick and easy that no dental anesthetic is required. Each tooth will be examined first. If we find any signs of early decay, we will gently treat that area before beginning.

When the tooth is ready, it will be cleaned and dried. An etching solution will be brushed on to the dry surface to roughen the area a bit so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light. And that’s it!

Once teeth are sealed, they should be cleaned and flossed just as carefully as before. Regular exams and cleanings are still very important, and we can monitor the condition of the sealant and the sealed teeth. Properly applied, sealants can last from three to five years, or even longer.

Who should consider sealants? Sealants are typically recommended when the permanent molars first erupt. Children’s enamel takes a while to become its strongest, and so these just-erupted teeth are more at risk for cavities. Sometimes Dr. Osuala will recommend sealants for primary (baby) teeth if needed. But even adults can benefit—talk to us if you are interested and we will let you know if sealants might be right for you.

Sealants are a simple, safe, and minimally invasive way to prevent cavities. Studies of sealed molars and premolars show a dramatic reduction in cavities compared to untreated teeth. Sealants are one of the most effective ways to defend your teeth or your children’s teeth from tooth decay. And as we’ve all heard—defense wins championships!

What to do about Sensitive Teeth

September 23rd, 2026

If you suffer from sensitive teeth, you already know the frustration of having a type of pain that is hard to deal with. Because tooth sensitivity is sometimes unpredictable, you can't necessarily take medication to ward off the pain like you could if you just felt a headache coming on.

However, there is still something you can do about sensitive teeth. Use the following tips to help put your sensitivity and pain problems with your teeth behind you!

Use the Right Toothbrush: Select a toothbrush made just for sensitive teeth, or the softest bristles possible. This helps you avoid putting any extra pressure on your teeth or gums.

Choose a Special Toothpaste: There are several good options for toothpastes made just for sensitive teeth today. Usually, toothpaste formulated for sensitive teeth will be fluoridated and use a non-abrasive formula. The toothpaste will help with the pain usually associated with brushing and flossing if you use it regularly.

Avoid Trigger Foods: You may have noticed certain trigger foods that cause tooth sensitivity and pain for you. Avoid these foods whenever possible, and if you absolutely must eat them, try to consume them in very small quantities. Trigger foods may include:

  • Foods with high acid content for example citrus fruits
  • Very hot or very cold foods
  • Hard or crunchy foods

Visit Our Office

If your sensitive teeth problem is too serious to manage on your own, a visit to our Maplewood & West Orange office may be in order. There are a couple of ways Dr. Osuala can help:

  • Fluoride Treatments: We can put a special fluoride formula on the most sensitive areas to help make your enamel stronger and to help lower pain levels.
  • Sealing Exposed Roots:In some cases, your roots become exposed due to a receding gumline, which in turn causes teeth sensitivity and pain. We can apply a dental sealant that protects the exposed roots and reduces your pain dramatically.

Are you at risk for oral cancer?

September 16th, 2026

Nearly 40,000 people are diagnosed with oral cancer annually in the United States, with more than 8,000 dying every year from the disease. Oral cancer has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body, most often, the lymph nodes in the neck.

Dr. Osuala and our team want you to know that cancers of the mouth and throat, which account for about three percent of all cancers in the United States, are largely preventable. However, we want you to know about certain risk factors that affect the likelihood of developing the disease.

  • Use of tobacco products including smoking cigarettes, cigars or a pipe, or chewing tobacco all elevate risk for developing oral cancer. Tobacco use especially, is a serious risk factor because it contains substances called carcinogens, which harm cells in your mouth.
  • Consumption of alcohol in excess can also increase your risk. If you drink alcohol regularly, you have an elevated risk of getting oral cancer. Alcohol abuse (more than 21 drinks in one week) is the second largest risk factor for the development of oral cancer, according to the Oral Cancer Foundation.
  • Excessive sun exposure. People who spend lots of time outdoors and do not use proper amounts of sunscreen or lip balm have a greater risk for developing lip cancer. Exposure to ultraviolet (UV) radiation from sunlight may also cause melanoma, the most serious type of skin cancer.

If you notice unusual lumps, bumps, or red or white patches in your mouth that don’t go away, sores that won’t seem to heal, persistent soreness, or pain or difficulty swallowing please consult Dr. Osuala and our team immediately.

Other factors that may influence your risk for developing oral cancer include:

  • Age: Oral cancer is typically a disease that affects older people, usually because of their longer exposure to other risk factors. Most patients diagnosed with oral cancer are over the age of 40.
  • Gender: Oral cancer strikes men twice as often as it does women.
  • A history with viral infections, such as human papillomavirus (HPV)
  • A diet low in fruits and vegetables

During your next visit, Dr. Osuala will examine your mouth for signs of oral cancer. If you have been putting off a visit to our Maplewood & West Orange office for your regular checkup, now is an excellent time to schedule one. Regular visits can be the first line of defense against oral cancer because we can identify early warning signs of the disease. Give us a call today!

Can You Repair Your Tooth Enamel?

September 9th, 2026

There are lots of ads out there for toothpastes that claim to repair damaged tooth enamel.

Can you treat cavities and tooth decay at home? Well, mostly, no, you can’t.

Can you strengthen your enamel at home? Very possibly—in some circumstances. Let us explain!

Cavities and tooth decay start forming when the enamel on the tooth’s surface breaks down. To discover what causes this breakdown, we need to see how chemistry works with our biology.

Tooth enamel is mainly made from calcium and phosphate ions. These minerals combine to form hydroxyapatite, crystals which make up around 95% of our enamel. Hydroxyapatite crystals are so strong that tooth enamel is the hardest part of our bodies. What can weaken a substance this strong?

Acids. Acidic foods and drinks, as well as acids created by the bacteria in plaque, strip away calcium and phosphate ions in enamel, weakening the surface of the tooth. This is a process called demineralization, and it’s the first stage of tooth decay. Left alone, weak spots will become bigger and deeper until they form cavities.

And tooth enamel, unlike the rest of your body, isn’t living tissue. It can’t regenerate. Once bacteria and acids have created a deep enough cavity, only Dr. Osuala can repair it by removing decay and filling the tooth.

Wait, this sounds a lot more like “No, you can’t repair your enamel” and much less like “It’s possible to strengthen your enamel.” But we’re not through!

Demineralization doesn’t equal cavities—yet. Careful attention to your habits and your diet can make a difference in whether your enamel continues to weaken or becomes stronger.

Our body’s first defense against demineralization is saliva. Calcium and phosphate ions in saliva bathe the teeth throughout the day, restoring the minerals which have been lost. This is called remineralization. Saliva also helps neutralize acids from the foods we eat. But with a diet heavy in acids, or a lot of plaque buildup, saliva just can’t keep up with the damage.

That’s where “enamel-repair” toothpastes come in. Toothpastes are available that contain hydroxyapatite to restore calcium and phosphates to weakened enamel. But for many of the most common enamel-repair toothpastes, the not-so-secret secret to their effectiveness is fluoride.

Dentists recommend fluoride toothpastes for several very good reasons. Fluoride is attracted to the minerals in tooth enamel and bonds with them. Once bonded, fluoride attracts the calcium and phosphate ions in saliva, helping restore lost minerals to the enamel. Even better, when fluoride bonds with the calcium and phosphate in our enamel, fluorapatite is created. This is a crystal even stronger and more acid-resistant than hydroxyapatite.

If you’re concerned about the strength of your enamel, and especially if you notice any signs of acidic erosion, talk to our Maplewood & West Orange dental team right away. Dr. Osuala can:

  • Recommend over-the-counter toothpastes or professional fluoride applications to help reverse early demineralization
  • Provide dental bonding, a crown, or a veneer to protect a tooth with serious erosion
  • Treat a cavity caused by more advanced tooth decay.

Keeping your enamel healthy at home can take many forms. By careful brushing and flossing to remove plaque, by watching the acids in your diet, by making sure you’re properly hydrated, and by using fluoride toothpaste, you can both reduce the risk of demineralization and help restore weak spots in your tooth enamel.

So, can enamel-repair toothpastes effectively repair your teeth? Yes, they can be effective—if demineralization is in its early stages and if you make them a regular part of your daily dental routine.
