When do children usually lose their baby teeth?

February 18th, 2026

Many parents worry that their children’s teeth are not falling out on time. A lot of concerned parents want to know: When will my child lose his or her first baby tooth? At what age should the last tooth fall out? Is there a specific order in which the teeth are lost?

Dr. Meuselbach and our team explain that a child's 20 baby teeth (primary teeth) typically come in by age three and begin to loosen and fall out on their own to make room for permanent teeth, which usually appear by the time your child is six. It is important to know that timing may vary, and girls typically lose their baby teeth earlier than boys. The last baby teeth will likely fall out by the time your child is 13.

So, which teeth do children lose first? Baby teeth tend to fall out in the order in which they came, which means the lower center incisors are usually the first to go when your child is between six and seven years old. The next teeth your child will lose are his or her top center pair, also called the upper central incisors.

It’s important to note that if a child loses a baby tooth early as a result of decay or an unforeseen accident, his or her permanent tooth may erupt early and potentially come in crooked due to limited space. If your child suffers an injury or has tooth decay, we encourage you to give us a call to set up an appointment with Dr. Meuselbach.

While we know some children couldn’t be more excited to lose their baby teeth, we know others are anxious about this childhood milestone. When your child starts to lose teeth, our team at Robert Scott Meuselbach DDS encourages you to stress the importance of proper dental care on a daily basis.

Remember to:

  • Remind your child to brush his or her teeth at least twice a day. Supervise and offer assistance as needed.
  • Help your child floss his or her teeth at bedtime.
  • Limit eating and drinking between meals and at bedtime, especially sugary treats and drinks, such as candy and soda.
  • Schedule regular dental visits for your child every six months.
  • Ask about the use of fluoride treatments and dental sealants to help prevent tooth decay.

Interproximal Cavities: The Inside Story

February 11th, 2026

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth which sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity which develops on one of those side surfaces of your teeth.

  • Discovering Interproximal Cavities

Clearly, a cavity between the teeth won’t be as obvious as other cavities. How will you know if a dental appointment is in order?

There are typical symptoms which can show up when you have a cavity. Chewing might be painful. You might feel pain or sensitivity when you eat or drink something which is hot, or cold, or sweet. But pain and/or sensitivity aren’t always present, especially when a cavity is just beginning to develop.

Regular exams are important so you can catch small cavities before they become more serious. That’s why, at your regular dental exams, Dr. Meuselbach will always check for any signs of decay on every surface of each tooth, including those places which aren’t easily visible. And that’s why X-rays can be an important tool for locating these tricky cavities.

  • Treating Interproximal Cavities

If Dr. Meuselbach and our team finds a cavity between your teeth, there are different treatment options available depending on the size of the cavity:

  • A typical cavity will require a filling. The decay will be removed, and then the area will be cleaned and filled. You’ll probably choose a filling material which can be matched to your enamel color if the restoration will be noticeable.
  • If decay has spread to the pulp chamber inside the tooth, a root canal is often the best treatment option, with a crown applied afterward to protect the tooth.
  • A tooth so decayed or infected that it cannot be saved might require extraction.

Dealing with any weakness in a tooth as quickly as possible is always better than waiting until a more complicated treatment option is needed. Of course, the best treatment is prevention, and, luckily for us, it’s not a complicated process at all.

  • Preventing Interproximal Cavities

In fact, it’s about as basic as it can be—brush and floss effectively. We recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gumline—places where bristles just can’t reach. The next time you get your teeth cleaned at our West Chester office, ask for tips on how to perfect your technique. And, if you have difficulty flossing, ask about alternatives such as water flossers and interproximal brushes.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If Dr. Meuselbach and our team find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with us to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

Canker Sores and Stress

February 4th, 2026

Canker sores are painful lesions that form in the soft tissues of the mouth, usually along the inner lips, under the tongue, and along the cheek walls. They are usually small and round, and take on a white or yellow hue. Though most are generally harmless and tend to heal on their own within a week or two of appearing, canker sores can be very irritating.

Only about one in five people develop canker sores. Of those who do, many develop them recurrently as a result of external factors. Though canker sores have been connected to allergies and hormonal changes, many people who are prone to developing canker sores find that their outbreaks are stress-related.

A combination of emotional stress and fatigue can be a perfect storm for the development of mouth sores. Some people say they are not under stress when canker sores form, but the sores appear several days after a stressful event or situation instead. Managing stress, reducing anxiety, and getting plenty of sleep may help prevent canker sores from forming and ensure that existing ones heal more quickly.

What to do if you develop canker sores

Do not be alarmed if you develop a canker sore. They are not contagious and are not harmful to your health. Over-the-counter oral numbing products can be used to manage pain, as can ice chips. Canker sores may heal faster if you apply milk of magnesia to them daily and avoid spicy foods that could irritate them.

You should contact your doctor if you find that your canker sores are unusually large or persist without healing for several weeks. Our team at Robert Scott Meuselbach DDS also recommends seeking out professional treatment if you experience extreme pain or a fever develops in association with a canker sore outbreak.

Can You Repair Your Tooth Enamel?

January 29th, 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. Meuselbach 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 West Chester dental team right away. Dr. Meuselbach 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.
