One of the most charming aspects of your baby’s beautiful smile is his brilliantly white teeth. But now that his adult teeth are coming in, the difference in color is very noticeable. Is this something to be concerned about? Happily, probably not.

Both baby teeth and adult teeth have the same basic structure. The inside of the tooth, the pulp, contains blood vessels and nerves. The pulp is covered by a layer of dentin, a hard, yellowish substance composed of living tissue that helps protect the pulp and transmits signals for pain, pressure, and temperature. Enamel is the outer protective covering of the tooth, and its natural color can vary from greyish-white to light yellow.

If primary and permanent teeth are so alike, how can they look so different? As with so many things, the difference lies in the details. In adult teeth, enamel is semi-translucent, so it will allow the color of what is beneath it to show through. And the color of the thick dentin beneath is naturally yellow. Baby teeth have a thinner layer of the yellowish dentin. And while their enamel is also thinner, the enamel in baby teeth is generally whiter and more opaque, so less of the underlying yellow from the dentin is visible.

The result of these small differences is that adult teeth are normally darker than baby teeth to begin with. And when a permanent tooth that is just a bit darker erupts next to a bright white baby tooth, it is going to look even more yellow than it actually is. Once all of the baby teeth in front have been replaced with adult teeth, you will have a much better idea of their real color without unflattering comparisons!

There are times when concerns about tooth color should be looked at by Dr. Guijon more closely.

• Unusual discoloration in teeth should be examined. Some discoloration is caused by medical conditions such as hypomineralization, some by environmental factors such as excess fluoride, some by trauma, some by medication. If you notice a discolored section of your child’s tooth, or the tooth has turned a different shade from the teeth around it, give us a call.
• Your child might have naturally whiter or yellower teeth simply as a matter of genetics. If your child is self-conscious about the color of his teeth, we can talk about whitening solutions when he is old enough to use them safely. Home whitening products should never be used on young children.

Give yourself time to adjust to your child’s new, adult smile. You will probably notice no difference at all once all of his permanent teeth come in. And keep those new teeth their brightest with consistent brushing and flossing, and regular checkups and cleanings at our Huntington Beach, CA office. This is the simplest prescription for a charming, white, and healthy smile at any age.

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 Huntington Beach, CA 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 Huntington Beach, CA 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. Guijon 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!

Are you looking to improve the appearance of your front teeth? Dental veneers are widely used to improve the appearance of front teeth and are a much more conservative option than a full dental crown. Veneers can be used to improve the appearance of staining, large gaps, large fillings, chipped teeth, or overall shape. Veneers are a thin covering over the front and biting end of the tooth used to restore the beauty of a smile. Over the years we have helped many patients who opted for veneers and now have the confidence to smile again.

Dental veneers are made in a lab from long-lasting porcelain materials. The shade can be chosen to a desirable color to whiten the appearance of your smile. Dental veneers are usually placed on the anterior, or front teeth, where the chewing forces are not as hard as the back teeth. The process of placing veneers is relatively easy requiring only two dental appointments. In some cases, only one appointment is needed. It depends on the fabrication process.

The first appointment is to “prep” the teeth and take an impression to be sent to a lab to fabricate the veneers. Veneers are fairly conservative in the preparation as it requires a small amount of space to be created on the face (front), bottom, and sides of each tooth to allow space for the veneer to be placed and look natural. You will leave the office with temporary veneers for the next week or two while the permanent veneers are being made.

The second appointment is to place the veneers and make minor adjustments if needed. What a difference it makes in the appearance of the teeth! If you’re interested in learning more, give Dr. Guijon a call today!

Here is some surprising yet worthwhile advice you might be hearing for the first time: Brushing after a meal can be incredibly bad for your teeth if you do it after eating certain foods.

Enamel is an extremely hard mineral on the exterior of each of your teeth. It’s actually the hardest substance in the human body: It’s even stronger than your bones! Its only weakness is that acids in the food we eat can easily destroy enamel.

Healthy teeth thrive in an environment that has the proper pH balance. That ensures your mouth doesn’t start the process of demineralization. That’s what happens when alkaline turns into acid, which attacks and softens the enamel on the surface of your teeth. Pores and fissures form, and that’s when the harmful bacteria go to work.

Our mouth’s pH level fluctuates depending on what we eat throughout the day. Examples of the most common highly acidic foods include citrus fruits, soda, and sugary foods. Highly acidic foods tip the balance of pH in your mouth from a healthy alkaline to a dangerous acid.

Can brushing your teeth immediately after a meal lead to even more damage? The answer is yes!

Eating highly acidic foods causes your teeth to be more susceptible. If you brush your teeth when they have been weakened by acids, even more destruction can happen to your enamel. Your toothbrush’s bristles will actually wear away some of your enamel. So it’s healthier to wait at least an hour after eating or snacking to brush.

Good preventive measures to take instead of brushing after you eat include:

• Rinsing or drinking water
• Chewing sugarless gum
• Consuming dairy or non-acidic foods to conclude your meal

These practices help produce saliva, which in turn restores a healthy pH level in your mouth and coats the teeth with minerals they need.

Once you’ve allowed time for your mouth to be restored to a healthy pH level, you may brush your teeth as you normally would. Keep in mind that acidic foods can weaken the enamel on your teeth and take the right measures to prevent spiking pH levels.

Most important, don’t forget to wait to brush at least one hour after you eat!
