If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The American Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The ADA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Dr. Kathleen Tavarez and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!

Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Menlo Park or San Carlos, CA office is carefully tailored to your child’s individual needs.

• For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
• For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
• For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

• Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
• Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
• Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

• Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

• Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

• MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

• Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

• Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Dr. Kathleen Tavarez to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

So, you just got your braces on, and you're wondering why you should continue visiting your general dentist since you’re seeing Dr. Kathleen Tavarez every other month. Patients always ask us if they should continue to see their dentist while in orthodontic treatment. In short, the answer is yes.

Today, we thought we would share a few reasons why it’s crucial to keep up with your regular visits with your dentist in addition to coming in for your regular adjustments at Tavarez Orthodontics.

One of the best reasons to visit your dentist while you undergo orthodontic treatment is to remove plaque and tartar. Having braces provides additional nooks and crannies in which food particles and bacteria can hide. Eventually, plaque and tartar can form around your brackets, bands or other appliances which can lead to cavities. Having your teeth professionally cleaned can help ensure most, if not all, plaque and tartar is removed. Even if you are undergoing clear aligner treatment, dental checkups and cleanings are equally as important.

The next reason to visit a dentist is to help protect your teeth from decalcification, or the loss of calcium in your teeth. A potentially serious condition in which white spots on your tooth surfaces, decalcification is irreversible and if left untreated, can lead to cavities. Decalcification is preventable; patients who cut down on sugary sweets and acidic foods, practice good oral hygiene, and visit their dentist regularly can help prevent decalcification.

The final reason we recommend visiting your dentist while you have braces is this: cavities can prolong your treatment. If you are interested in completing your orthodontic treatment on time and without any delays, visiting your dentist every six months or as recommended can go a long way toward making that a realistic goal. Your dentist can provide fluoride treatments or other treatments that strengthen your teeth and protect them from cavities.

Making sure to visit your dentist will help ensure your teeth look their best once your braces come off. If you do not have a general dentist and would like a recommendation on finding one in the Menlo Park or San Carlos, CA area, please give us a call or let us know at your next adjustment appointment!

You may have noticed that we specialize in orthodontics and dentofacial orthopedics. And while most people we talk to have heard of orthodontics, many are confused by the dentofacial orthopedics part of the title. Today, Dr. Kathleen Tavarez and our team thought we would explain the difference.

While orthodontics entails the management of tooth movement, dentofacial orthopedics involves the guidance of facial growth and facial development, which occurs for the most part during childhood, and is a reason why kids are often the best candidates for receiving dentofacial orthopedic therapy. Dr. Kathleen Tavarez will examine and monitor your child’s growth to determine when starting treatment will be most effective. If your child begins orthodontic treatment before his or her adult teeth have erupted, it is known as Phase-One treatment. During this phase, Dr. Kathleen Tavarez will use treatments designed to correct your child’s jaw growth and make sure that the jaw bone is properly aligned before beginning the next phase of treatment, which usually involves placing braces to straighten your child's teeth.

Dentofacial orthopedics is also used to treat adult patients at Tavarez Orthodontics, however, this process may involve surgery. With our younger patients, we know the jaw bones are still forming, making it easier for our team at Tavarez Orthodontics to control bone growth and tooth movement. Adults, however, are a different story; their bones are no longer growing, and their jaw bones have hardened, so it is more difficult to adjust the bite and move teeth into proper alignment. Dr. Kathleen Tavarez may recommend surgery to adjust the jaw bone and establish the proper bite alignment before beginning treatment.

Because our team at Tavarez Orthodontics is skilled in both areas, we are able to diagnose any misalignments in the teeth and jaw as well as the facial structure, and can devise a treatment plan that integrates both orthodontic and dentofacial orthopedic treatments.

We hope that helps! To learn more about dentofacial orthopedics, and to find out if this type of treatment is right for you, please contact our Menlo Park or San Carlos, CA office and schedule an initial consultation for you or your child. It’s never too late to get a great smile, and we can’t wait to help you or your child get started.
