What are dental sealants, who should get them, and how long do they last?
March 29th, 2023

Dental sealants are an excellent way to protect children’s teeth from tooth decay by coating them with a thin plastic material. Their teeth look and feel like normal, but they are protected from plaque build-up and decay early on. Dr. Rick Johns and our staff recommend sealants as a preventive measure for children before any decay appears on their teeth.
Who should get dental sealants?
Dental sealants are intended for young children as soon as their first teeth come in. Decay is most common in the molars, so taking your child to Rick Johns Dental for sealants right when you see the molars grow in gives your child the best chance to fight tooth decay.
A child’s first set of permanent molars grow in between ages five and seven, while the second permanent molars come in between 11 and 14 years of age. Some teens and adults who don’t have tooth decay may get sealants as well, but it is less common.
How long do dental sealants last?
Once the sealant has been placed on the teeth, it lasts up to ten years. Expect to have Dr. Rick Johns check the sealant at every visit to our Highland, IN office, which should be twice a year. We will look at the sealant and determine if it needs to be replaced.
What is the process of getting sealants?
Applying sealants is a simple, pain-free procedure that is done quickly at Rick Johns Dental. There is absolutely no effect on the tooth structure from sealants.
For starters, the teeth are cleaned carefully, then dried with an absorbent material. A mild acid solution is applied to them to roughen them slightly. This is done so the sealant can bond properly to the teeth. Then the teeth are rinsed and dried, and the sealant material is painted on and dried with a special light.
Molars are susceptible to decay early on, which is why sealants are an important treatment to get for your children’s first set of teeth.
Can You Stop a Cavity Before It Starts?
March 29th, 2023

You’re busy getting ready for your day, and of course you’re starting your day off right by looking after your dental health. A two-minute brushing, some careful flossing, and—wait, is that a white spot on your tooth?
If your mirror reveals a patch of white on your enamel, it could be a symptom of early tooth decay. Does this mean a cavity is necessarily in your future? Perhaps not, if you act promptly to reverse the damage!
Cavities, after all, don’t suddenly appear in our mouths. Tooth decay is a process, and it begins with a weak area in the enamel that often appears as a white spot on the tooth. These weak spots are known as “incipient cavities,” because they can easily become cavities if left untreated.
Why do these weak spots occur? And how can we repair them? Let’s look at some tooth science.
- Demineralization
Your tooth enamel is one of the marvels of the human body. Enamel is mostly made of calcium and phosphate ions, minerals which combine to form hydroxyapatite crystals. These crystals create a substance so strong that tooth enamel is the hardest part of the body—harder even than bones.
But it’s not indestructible! If you don’t care for your teeth with regular brushing and flossing, you’re leaving your enamel open to attack.
The bacteria in plaque convert the nutrients they get from the food we eat—especially sugars—into acids. These acids strip away the calcium and phosphate minerals which are the building blocks of our enamel, weakening the surface of the tooth.
Over time, these weak spots get bigger and deeper as bacteria and acids continue to attack the tooth surface. Eventually, cavities form, damaging the enamel surface, and, over time, even reaching into the dentin and the pulp inside the tooth. Once a cavity has formed, you need dental treatment to clean away the decay and repair the tooth structure.
The good news is that, when caught early, it’s possible to rebuild a weak spot in the tooth enamel before a cavity can fully develop.
- Remineralization
While acids strip minerals from your enamel, your body is also replacing those lost minerals all throughout the day. How does this balancing act take place? With the help of saliva.
The very minerals which acids strip from your enamel are found in saliva. Saliva bathes your teeth with calcium and phosphate ions which, in turn, bond with your enamel to rebuild and restore enamel strength. When missing minerals are replaced like this, it’s called remineralization.
But this careful balance of demineralization/remineralization can become upset. If you neglect brushing and flossing, for example, plaque buildup will increase the amount of acids your teeth are exposed to. This means that your body won’t be able to replace the minerals as quickly as they are stripped away, and the result is a white patch on your tooth where the enamel has lost mineral strength.
If you’re surprised by the appearance of a white spot on your tooth, it’s a good idea to visit our Highland, IN office for a diagnosis. If the spot is caused by an incipient cavity, Dr. Rick Johns can provide you with some options to restore your enamel’s strength.
Fluoride toothpastes and fluoride treatments are some of the most efficient ways to remineralize your teeth. Fluoride is attracted to the minerals in your enamel. It bonds with the tooth surface, and, once there, it helps attract the calcium and phosphate ions in your saliva to restore lost minerals and repair weak spots.
But fluoride does more than just restore your tooth’s strength—it improves it! Fluoride ions join with the calcium and phosphate minerals in your teeth to form fluorapatite crystals, which are even larger and stronger than hydroxyapatite crystals.
Early treatment is your best opportunity to reverse the early stages of tooth decay. Keeping up with your brushing and flossing, eating a dental-healthy diet, seeing Dr. Rick Johns regularly, and treating incipient cavities promptly will help ensure there are no unwelcome surprises in the mirror—just beautiful, healthy smiles!
Oral Health for the Young Adult
March 22nd, 2023

Young adults often have the reputation of not taking good care of themselves. You may feel invincible, and not realize how much your behaviors now can affect your health later in life. Oral health is one area that is easy to neglect now, but that can lead to serious financial and quality of life consequences later.
Follow a Good Oral Care Regimen
If you don’t already do so, it’s time to brush, floss, and rinse as Dr. Rick Johns taught you. Brush at least twice a day or after meals, and floss your teeth every day. If recommended, use mouthwash to kill germs in your mouth. If you are not able to brush your teeth after eating, swish water around in your mouth to remove the food from your teeth. Leaving carbohydrates in your mouth allows bacteria to ferment it and produce acid, which can destroy your tooth enamel and put you at risk for decay.
Visit Our Office Regularly
Young adulthood can be a challenging time when it comes to medical care. Your parents are no longer paying for your health insurance or taking you to your appointments. You may not worry much about getting regular cleanings and exams, especially if you’re paying for them yourself.
However, young adults have a lot to gain from visiting our Highland, IN office regularly. We can check for signs of problems and fix them early, which can save thousands of dollars and, ultimately, your teeth. These are some examples of what Dr. Rick Johns and our hygiene team can do for you.
- Get rid of plaque so it does not develop into tartar and cause periodontitis.
- Identify and fill small areas of tooth decay to prevent it from progressing.
- Examine your gums for signs of gingivitis, or early gum disease.
Consume a Tooth-Healthy Diet
A nutritious diet is not just for preventing heart disease and diabetes later in life. It also supports your teeth. Make sure to get plenty of calcium, such as from dairy products, canned fish, and leafy green vegetables to allow for strong teeth. Also, limit sticky foods and sugary sweets.
St. Patrick's Day
March 15th, 2023

On March 17, everyone has a little Irish in them. St. Patrick’s Day is a joyous celebration of Irish heritage. The holiday originated as a commemoration of Saint Patrick, who brought Christianity to Ireland. The saint arrived in Ireland in 432 and earned the reputation of a champion of Irish Christianity. March 17th, the day of St. Patrick’s death, has been commemorated by the Irish for over 1,000 years. St. Patrick’s Day is still observed as a religious feast day by several Christian denominations, but it is better known in the public imagination as a rich celebration of Irish culture.
St. Patrick’s Day has been an official public holiday in Ireland since 1903. Each year, the Irish celebrate with a several-day festival that includes theater performances, music, fireworks, and festive parades. The celebration is also a public holiday in Northern Ireland, Montserrat, and Newfoundland and Labrador. In other parts of the world with heavy Irish populations, it is an unofficial celebration of Irish heritage. Parts of Great Britain, Canada, Argentina, South Korea, Switzerland, New Zealand, the United States, and Australia commemorate the holiday each year. Typical celebrations in these countries include drinking green beer, wearing green, eating traditional Irish foods, parades, and shamrock decorations.
Many people, Irish and non-Irish alike, take part in the “wearing of the green” on St. Patrick’s Day. In fact, the color originally associated with Saint Patrick was blue. His use of shamrocks to explain the Holy Trinity to the Irish made the green clover emblematic of the holiday, leading to the traditional green attire worn by thousands on St. Patrick’s Day. Other little-known facts about St. Patrick’s Day include the following:
- Each year, the United States and Ireland face off in a rugby competition called the “St. Patrick’s Day Test.”
- Montreal celebrates the holiday with an annual parade, which has been held each year since 1824. The Montreal city flag even features a shamrock in its corner, as a nod to its Irish heritage.
- The Guinness World Records named St. Patrick’s Day the “Friendliest Day of the Year.”
- Along with Valentine’s Day, St. Patrick’s Day is one of the most widely celebrated saint’s day in the world.
No matter your cultural heritage, St. Patrick’s Day is a great time to let loose and celebrate your inner Irish-ness! Don your greenest attire and exclaim “Erin go Bragh!” (Ireland forever!) to everyone you meet. From Dr. Rick Johns - have a great St. Paddy’s day!
