Just What Is a Cavity, Anyway?

January 22nd, 2025

The grownups in your life encourage you to brush and floss, eat healthy foods, and visit us in the dental office for exams and cleanings. Why? Because we all want to help you prevent cavities.

So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria that cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals that keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, which could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth that keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

  • Do: Feed yourself foods that are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

  • Don’t: Feed bacteria foods that are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

  • Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

  • Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

  • Do: Visit our Salinas office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest. We even have special coatings called sealants that can protect your teeth from plaque.

  • Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Dr. Jennifer Lo and Dr. Jacqueline Nguyen if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

Dental Fear in Children: Brought on by parents?

January 15th, 2025

A study conducted in Washington State in 2004 and another conducted in Madrid, Spain in 2012 both reported findings that support a direct relationship between parents’ dental fear and their child’s fear of the dentist.

The Washington study examined dental fear among 421 children ages 0.8 to 12.8 years old. They were patients at 21 different private pediatric dental practices in western Washington state. The Spanish study observed 183 children between the ages of seven and 12 as well as their parents.

The Washington study used responses from both parents and the Dental Sub-scale of the Child Fear Survey Schedule. The survey consisted of 15 questions, which invited answers based on the child’s level of fear. The scale was one to five: one meant the child wasn’t afraid at all, and five indicated he or she was terrified. The maximum possible points (based on the greatest fear) was 75.

Spanish researchers found a direct connection between parental dental fear levels and those among their kids. The most important new discovery from the Madrid study was that the greater the fear a father had of going to the dentist, the higher the level of fear among the other family members.

Parents, but especially fathers, who feared dental procedures appeared to pass those fears along to every member of the family. Parents can still have some control over fear levels in their children. It is best not to express your own concerns in front of kids; instead, explain why going to the dentist is important.

Dr. Jennifer Lo and Dr. Jacqueline Nguyen and our team work hard to make your child’s visit at our Salinas office as comfortable as possible. We understand some patients may be more fearful than others, and will do our best to help ease your child’s anxiety.

Toothpaste Guide

January 8th, 2025

Between the huge number of toothpaste brands on the market today, the different flavors, and claims from most to do different things, it isn’t surprising that people feel so confused when it comes to something that should be as simple as buying a tube of toothpaste. This guide will help you identify the common ingredients in toothpaste, and help you understand the important factors to consider before buying toothpaste again.

Toothpaste comes in gel, paste, and powdered forms. When it comes to the type of toothpaste, the choice is more a matter of preference.

Basic Ingredients

  • Abrasive Agents – Abrasive agents are the scratchy substances added to toothpastes to help in the removal of food particles, bacteria, and minor stains. Calcium carbonate is one of many abrasive materials, and arguably the most common.
  • Flavor – When toothpastes are flavored, they almost always have artificial sweeteners to enhance the flavor of the toothpaste and increase the likelihood that you’ll use it. Flavors run the gamut from traditional mint to cinnamon that may appeal to adults, and bubble gum or lemon lime – flavors to target children.
  • Humectants – Humectants are moisturizing agents that keep paste and gel toothpastes from drying out. Glycerol is commonly used as a humectant.
  • Thickeners – Thickeners are used to give toothpaste its distinctive consistency, and to make it maintain a uniform consistency and come out of the tube easily.
  • Detergents – Sodium lauryl sulfate is the most common detergent used in products that foam up, like toothpaste does in your mouth.

What to Look For in Toothpaste

Fluoride is naturally occurring mineral. It is the most important ingredient to look for in a toothpaste. Although there are people who argue against using fluoride toothpaste, dental professionals like Dr. Jennifer Lo and Dr. Jacqueline Nguyen emphasize that the fact that the incidence of tooth decay has decreased so significantly in the past 50 years is because of fluoridated toothpaste.

The suggestion that fluoridated water gives you enough fluoride to protect your teeth is wrong. Fluoride toothpaste is the best cavity protection there is. In addition to strengthening tooth enamel and protecting teeth from acid erosion (from acidic foods and drinks,) it remineralizes the surfaces of teeth that are suffering from early acid damage and may prevent developing tooth decay from worsening.

Tartar Control

Tartar is the result of hardened plaque buildup on the teeth. Good oral hygiene and in between twice yearly cleanings from a dental hygienist are the best defense against plaque buildup. Plaque turns to tartar when people neglect their oral hygiene. Over time, tartar can build up on teeth and under the gums, increasing the risk of gum disease.

Your best bet is to use a toothpaste that has a combination of anti-plaque agents. Products containing more than one plaque reducer may be more effective than products that only one. Common ingredients to look for are zinc citrate or pyrophosphates. Triclosan is an antibiotic that is believed to kill bacteria in the mouth, and it can be found in some anti-plaque toothpaste.

Look for toothpaste that bears the seal of the American Dental Association. That seal is an endorsement of the ADA – and it means that many dentists agree that that particular toothpaste does what toothpaste is designed to do. We can also recommend toothpaste to meet your specific oral health concerns at your next visit to our Salinas office.

Make your child’s next visit to our office great!

January 1st, 2025

If you have been bringing your baby in for regular checkups since that first tooth arrived, you might expect that he or she is already familiar with Dr. Jennifer Lo and Dr. Jacqueline Nguyen and our staff. Often, though, months pass between visits, which is a very long time for a child. How can you make your preschooler’s return visit a happy one? We have some suggestions!

Before Your Visit

  • Prepare your child for her visit. Simple explanations are best for a young child. You might tell your daughter that a dentist is a doctor who helps keep her teeth strong and healthy. Let her know a bit about what will happen. Being told, “You will sit in a special chair,” or, “Can you open wide so we can count your teeth?” will give her some idea of what it’s like to visit our office.
  • There are many entertaining books for young children about visiting the dentist. Reading some of these to her for a few days before the appointment will let her know what to expect.
  • Use playtime to prepare. You might count your daughter’s teeth or let her “play dentist” and brush the teeth of her favorite doll or stuffed animal.

When You Arrive

  • Your attitude can be contagious! If you treat a visit to the dentist like any other outing, chances are your child will too. Your calm presence is exactly what your child needs.
  • You might want to come a bit early to let your son explore the office. Bring a favorite toy or book to keep him entertained if you need to. A favorite stuffed toy can be a comfort in an unfamiliar place.
  • If you are with your child during his checkup, follow our lead. Don’t be concerned if your child seems uncooperative at first or even throws a tantrum—we are used to working with children, and have techniques to make his experience as relaxed and as positive as we possibly can.
