When you were younger, and you brushed your teeth without any help for the first time, it was a big step. It meant you’d learned the right way to brush to keep your teeth and gums healthy. But why does brushing help keep you healthy? Let’s talk about plaque!
- What Is Plaque?
Plaque rhymes with “attack,” and that’s just what it does to your teeth. If you don’t brush for a few days (which is a bad idea!), plaque is the reason for that fuzziness you feel when you run your tongue over your teeth.
If your teeth feel fuzzy, that means that plaque has been building up for a while. But how does it begin?
Plaque is made up of saliva, bits of food, other liquids, and tiny little organisms called bacteria. While most of the bacteria in our bodies don’t bother us—and some even help us—the bacteria in plaque are not so helpful.
Plaque starts with a type of bacteria that stick to the teeth, loosely at first, and then more strongly. Within hours, they join with saliva, bits of food, and other bacteria and bacterial products to make a very sticky film. This film is plaque.
Why is it so important to brush plaque away every day? As Dr. Eduardo Perez will tell you, plaque can cause cavities and hurt your gums.
- How Does Plaque Cause Cavities?
Bacteria are like us—they need food. The bacteria in plaque especially like the sugars we eat. (That’s why you shouldn’t have too much junk food or candy in your diet.) Bacteria change these sugary building blocks into a kind of acid, and because plaque is sticky, the acids stay on your teeth.
These acids breaks down the enamel, that hard coating which covers teeth. Tiny weak spots can grow and become holes in the enamel. We call these holes cavities, and your dentist can repair them by cleaning away the decay and putting a filling in your tooth to protect it.
But it’s best to prevent cavities from ever starting by brushing and flossing. Even though plaque is sticky, it is easy to brush away when you do it every day.
- How Does Plaque Hurt Your Gums?
The gums surround our teeth and help protect them, but they are also delicate. When plaque builds up, it can irritate your gums.
You might notice that your gums get red, feel sore when you brush, or look puffy. You might have bad breath that doesn’t go away. All these are signs that your gums are reacting to the plaque around them.
The good news is that careful brushing and flossing can usually fix these problems. Talk to Dr. Eduardo Perez about taking good care of your gums.
- Can We Fight Plaque?
Yes! From the time you were small and learned how to brush, you’ve been learning how to fight plaque.
- Brush at least twice a day for two minutes, and be sure to brush all around each tooth and the gums.
- Floss to remove plaque from where it hides between the teeth and near the gums.
- Visit our San Antonio, Texas office for a cleaning, to remove plaque from hard-to-reach places and to learn the best ways to brush and floss.
As soon as you finish brushing, plaque starts to build up again. But no need to worry! Keep brushing, flossing, and visiting us for regular cleanings, and all your careful work will be rewarded will a beautiful, healthy smile.

Pediatric dentists strive to make your children’s visits welcoming and worry-free, and, we want the same for you! Ask us about any questions you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your child’s experience can be. And if X-rays are a concern, we can put your mind at ease here as well.
What Exactly Are X-rays?
Sometimes parents feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.
Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is termed radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.
We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.
Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.
How Do Dental X-rays Work?
An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.
Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs.
There are different types of common dental X-rays which are used for pediatric exams, including:
- Bitewing X-rays, which are used to check on the health of the back teeth.
- Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
- Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
Why Do We Need X-rays?
If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:
- Cavities between teeth
- Damage to the tooth’s pulp which might require root canal treatment
- Injuries to teeth or roots after trauma
- Abscesses, tumors, or other conditions that might be causing swelling or pain
- Unusual position or development of the teeth before and as they erupt
- Alignment and development of wisdom teeth
X-rays can also serve an important preventative role, by discovering small problems before they become major ones.
How Do Dentists Make Sure Your Child’s X-rays Are as Safe as They Can Be?
First of all, the amount of radiation patients are exposed to with a dental X-ray is very small. In fact, a set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Eduardo Perez and our team are committed to making sure young patients are exposed to as little radiation as possible.
Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.
The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:
- We take X-rays only when they are necessary.
- We provide protective gear, such as apron shields and thyroid collars, whenever needed.
- We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
- We set exposure times based on each child’s size and age.
X-rays play an important part in helping us make sure your child’s teeth stay their healthiest. If you have any concerns, contact our San Antonio, Texas office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

Sometimes the reason for a poor night’s sleep is obvious. Maybe your child watched a scary movie. Or loaded up on sugar before bed. Or can’t get to sleep after a night of computer screens or video games. Not much we can do about these problems.
Sometimes, though, the cause of your child’s sleep difficulties is dental in origin, and that is something Dr. Eduardo Perez can help with.
Teeth grinding, or bruxism, is a very common childhood dental problem. While children with this condition sleep, their jaws clench and their teeth grind against each other throughout the night. When to suspect children might suffer from bruxism? When they experience:
- Frequent headaches or facial pain
- Waking with a sore jaw, or popping or clicking jaw sounds through the day
- Teeth which are chipped, cracked, flattened, worn down, or sensitive
- Waking up tired, because grinding affects the quality of sleep
- Siblings who complain about nocturnal grinding noises, which affect the quality of their
Pain and fatigue are unpleasant enough, but there are additional serious consequences for those who suffer from bruxism. Our jaws are extremely powerful, and clenching and grinding can put hundreds of pounds on pressure on teeth and jaws over a few hours of sleep.
These forces can lead to damaged teeth and dental work, and problems with the temporomandibular joint, or TMJ, the complex hinge that allows our jaws to move up and down, back and forth, and side to side.
Clearly, prevention is clearly a much better option for a healthy smile. And one of the simplest and most effective treatments for preventing the damage caused by bruxism is a night guard.
Night guards fit over the affected teeth to prevent them from touching directly, saving tooth and enamel from injury and wear. Not only do night guards prevent contact, they spread the biting forces of the jaw over the surface of the guard to greatly reduce their impact. And because they also stop the jaw muscles from clenching tightly, there’s no excess stress placed on the temporomandibular joint.
For all these reasons, a night guard is pretty much a slam dunk for adults who grind their teeth. But for children, it’s not necessarily an automatic decision. Why?
- If tooth grinding is mild and appears to be limited to baby teeth, children often outgrow the condition. Your dentist can let you know if you need to do more than monitor the situation.
- Sometimes it seems like your child’s smile changes from day to day. Between losing baby teeth and erupting adult teeth, this beautiful smile is a work in progress. A fitted night guard might not be a perfect fit while your child’s teeth are still coming in and shifting position.
- Finally, jaw and facial pain can also be caused by problems with your child’s bite or misaligned teeth, and that might mean that an orthodontic consultation is in order.
But if you suspect your child is suffering the effects of night time grinding and clenching, give our San Antonio, Texas office a call. A thorough examination will provide you with the best diagnosis and solutions for helping your child retain a healthy smile and regain a healthy night’s sleep.
And if a night guard is recommended, a dental professional is the best person to see for the most effective night guard.
While over-the-counter products are available, a custom night guard is designed to fit your child’s individual teeth and mouth perfectly. Impressions or 3D scans are taken in the office, and a guard is fabricated with the precise shape, strength, and thickness needed to protect young teeth. And, as a bonus, custom night guards offer the most comfortable fit for the most comfortable night’s sleep.
Scary movies, a late night sugar rush, mesmerizing video screens—not much we can do about those! But if your child is suffering lost sleep and painful mornings because of tooth grinding, give us a call. A night guard just might be the key to sweet dreams.

Quick trivia question: define “mamelon.” Some kind of warm blooded animal? No, not a member of the mammal clan, but good guess. A fruit of the gourd family? Nope! There are watermelons, and honeydew melons, and even canary melons, but no ma-melons. Those little rounded bumps you notice on the edge of your child’s permanent incisors when they first emerge? We have a winning answer!
- Why Do We Have Mamelons?
We have eight incisors, or biting teeth, in the front of our mouths—four on top and four on bottom. Mamelons are actually a clue as to how these incisors were formed. Even before a baby is born, the permanent teeth begin to take shape. Three different groups of cells develop to form the incisal edge of these front teeth. As they fuse together, they create three lobes of enamel on the erupting edge of the tooth. It’s these lobes, or bumps, that give the teeth a serrated appearance.
Whether your child’s mamelons are quite prominent or barely noticeable, if you are worried about them, relax! They are almost always a temporary part of your child’s smile, and disappear over time with chewing and normal wear. But what if the mamelons overstay their welcome?
- Cosmetic Concerns
Because mamelons are composed of enamel, without the underlying dentin layer found in the body of the tooth, they can appear translucent or a bit different in color. They might wear away unevenly, leaving the tooth edges looking misaligned. Or, they might not wear away at all if your child’s tooth eruption is delayed. Talk to Dr. Eduardo Perez if mamelons are a cosmetic concern for you or your child. You might discover that they are wearing away naturally, or we can discuss ways to polish or smooth them down if needed. This is a painless procedure that doesn’t require an anesthetic. Generally, however, this is a matter where time will resolve the issue for you.
- Orthodontic Implications
Occasionally, mamelons might become a topic of discussion for orthodontic reasons. Sometimes, mamelons do not wear away over time because of a malocclusion (misaligned bite). Your orthodontist will let you know your child has a bite problem and can explain treatment options. Your orthodontist might also suggest smoothing away the mamelons to ensure that the edges of the incisors align correctly and symmetrically while the teeth are in the process of straightening. Again, this is not always considered a necessity, so weigh your options with your dental care provider.
So, if you notice that your child’s beautiful new teeth are bumpy or serrated as they erupt, don’t be concerned! If you have any questions about mamelons, talk to Dr. Eduardo Perez at your next visit to our San Antonio, Texas office. This is a natural occurrence and most likely just a temporary “bump” in the road. Soon enough, mamelons will be a memory—and the answer to a pretty difficult trivia question.
