Oral Hygiene Thousand Oaks

Why is oral hygiene so important?

Adults over 35 lose more teeth to gum diseases (periodontal disease) than from cavities. 75% of adults are affected by gum disease in their lifetime. The dental community has made clear that the best way to prevent cavities and periodontal disease is by committing to good oral hygiene.

Periodontal disease and decay are both caused by bacterial plaque. Plaque is a colorless film, which sticks to your teeth at the gum line, and is constantly building up on your teeth. In order to fight plaque and prevent periodontal disease, we recommend brushing and flossing every day.

How to Brush

Dr. Saremi and Dr. Johnstone recommend investing in a soft to medium tooth brush. Start by brushing your teeth. Position the brush at a 45 degree angle where your gums and teeth meet. Brush the outside surfaces of your teeth gently and in a circular motion several times. Focus on getting the bristles between the teeth with light pressure.

When you are done cleaning the outside surfaces of all your teeth, follow the same directions while cleaning the inside of the back teeth.

When cleaning the inside surfaces of the upper and lower front teeth, try to keep the brush in a vertical position. This will help you reach those areas and clean the area effectively. Whether you are cleaning the inside or outside surfaces of your teeth, don't forget to also gently brush the surrounding gum areas as well.

Finally, brush the biting surfaces of your upper and lower teeth. As always, brush gently and focus on the back teeth very well as those perform a majority of the chewing in your mouth. After you have finished brushing, rinse your mouth out with water or mouth wash to remove any loose plaque.

How to Floss

Flossing is one of the best ways to prevent tooth decay and gum disease from occurring between your teeth. Flossing is very effective if performed correctly and this article will explain exactly how to do that.

Start by grabbing a piece of floss no less than 18 inches in length and wrap it around both of your middle fingers. Position your thumb and forefinger of each hand under the floss and begin inserting the floss in between your upper teeth. Gently position the floss against each side-surface of the tooth and create a back and forth motion with the piece of floss. Focus on wrapping the tooth with the floss in a C-shape to maximize efficiency as you floss up and down the tooth. Don't forget to go slightly below the gum surface and stop when you feel resistance.

Follow the same process as the upper teeth when cleaning the bottom teeth.

Some soreness and bleeding is common when first starting to floss. This should stop as you get better at flossing and your gums develop more strength. Rinse your mouth after flossing to ensure all loose plaque is removed from your mouth.

Professional Cleaning

Good oral hygiene is a great way to prevent gum disease and cavities, however, we recommend a professional cleaning every 6 months to a year to prevent Calculus buildup. A professional cleaning is the best way to ensure you are following proper oral hygiene procedures and that your teeth are free of tooth decaying substances.

Child Dentistry Thousand Oaks

What to expect for your first visit?

Your child's first official dental visit should be just after your child's 3rd birthday. This should be a routine visit and involve very little treatment. To ensure a relaxing visit for your child, we may ask that you assist in the exam by holding your child or comforting them as we proceed.

We will examine your child's teeth and gums to ensure good oral hygiene is happening at home. If we suspect that your child may have some tooth decay, X-Rays may need to be taken to inspect the extent of damage done to the teeth. After the inspection, we will clean your child's teeth with a topical fluoride to help prevent teeth against decay.

Here are some "First Visit" tips:

  • Come in before your appointment for a tour of the office.
  • Read books with them about going to the dentist.
  • Review with them what the dentist will be doing at the time of the first visit.
  • Speak positively about your own dental experiences.

During your first visit the dentist will:

  • Examine your mouth, teeth and gums.
  • Evaluate adverse habits like thumb sucking.
  • Check to see if you need fluoride.
  • Teach you about cleaning your teeth and gums.
  • Suggest a schedule for regular dental visits.

Preventative Care?

With advances in dental technology, children have a better chance of preventing tooth decay. Our office relies on the latest in dental sealants technology to proactively protect your child’s teeth. Dental sealants are a white plastic resin that coats the biting surfaces of your child's teeth to give them an added layer of protection against plaque and other tooth decaying elements. Dental sealants are just one of the ways we can provide preventative care for your child's smile.

Cavity Prevention

Most tooth decay stems from a poor diet and lack of brushing. Choosing to stay away from sugar and making sure your child brushes and flosses routinely can help significantly. We understand that keeping your child away from sugar is next to impossible these days. Therefore, after a sugary meal, make sure your child rinses properly with some water to prevent acidic or bacterial buildup in their teeth.

Acidic reactions and bacteria from food/candy can cause major tooth decay. Saliva is one way to fight against those bad agents and can be improved with proper diet. If a person has thinner saliva, food is processed and swallowed quicker. On the other hand, if your saliva is thick and viscous, food - bacteria and acid - will remain in your mouth longer and thus, could cause more damage to your teeth and gums.

Tips for cavity prevention

  • Limit frequency of meals and snacks.
  • Encourage brushing, flossing and rinsing.
  • Watch what your child drinks.
  • Avoid giving your child sticky foods.
  • Make treats part of meals.
  • Choose nutritious snacks.
Baby teeth are just as important as adult ones. They not only help your child eat properly but also provide developmental support for their speech, chewing, facial appearance and other necessary activities. For these reasons and more, it is necessary to ensure proper oral hygiene care for your children.

Teeth Cleaning In Thousand Oaks

A dental cleaning, or prophylaxis, is a cleaning treatment performed by your dentist in which they focus on cleaning plaque and calculus from your teeth and gums. Teeth cleaning is a very important dental procedure which can prevent many periodontal diseases.

Some benefits:
  • Plaque removal. Plaque buildup on teeth is a common cause for periodontal disease such as tooth decay and gingivitis. Brushing and flossing are good ways to help prevent plaque from building but it's difficult to remove all of it. Our dentists have the specialized tools and experience necessary to remove all damaging plaque buildup that brushing and flossing simply cannot accomplish.
  • Better breath. Bad breath (or halitosis) is a common symptom of poor oral health. Tooth decay, plaque buildup, and decaying food/bacteria in your mouth are all contributors of bad breath. By having your teeth and gums treated by a dentist, these issues can be addressed and consequently, your breath will improve.
  • A great smile! Getting your teeth cleaned helps you look like a superstar! Removing damaging materials from your mouth will brighten your smile and help prevent the discoloration of your teeth.
Dental cleaning only takes one office visit and is a routine procedure. As plaque buildup is a constant battle, we recommend a dental cleaning twice annually as a preventative measure. For clients suffering from periodontitis, we recommend every 3-4 months. Periodontal disease can not always be completely reversed, and for this reason, we believe preventative measures like teeth cleaning should be taken very seriously.

Periodontal Maintenance Thousand Oaks

Gum infections, otherwise known as periodontal diseases, can be very dangerous. Dental plaque, gingivitis, and other malicious gum agents can affect the gums and endanger the support of your natural teeth. We recommend good oral hygiene practices such as brushing and flossing to help fight these agents.

Why is oral hygiene so important?

Adults over 35 are at higher risk from losing teeth due to gum disease than from cavities. To prevent gum disease and other tooth decay, we recommend brushing and flossing every day.

A major contributor to periodontal disease and tooth decay is bacterial plaque. Plaque is a colorless film that accumulates on your teeth at the gum line. This constant buildup can be prevented by brushing and flossing each day and eating an appropriate diet. Plaque buildup can eventually turn into a harder substance known as Calculus (or tartar). Dental cleanings and other tools can remove these buildups to help ensure healthier smiles.

Other important factors affecting the health of your gums include:

  • Smoking
  • Diabetes
  • Stress
  • Clenching and grinding teeth
  • Medication
  • Poor nutrition

Periodontal Disease

Plaque stems from bacteria in food and other toxins that remain in the mouth throughout the day. This bacteria irritates the gums and can cause them to bleed easily. Prolonged gum irritation and poor health will weaken gums and therefore the natural support for your teeth. If not treated, gum disease (periodontal disease) can lead to tooth separation and eventually tooth loss.

Preventing Gum Disease

We recommend brushing and flossing every day when you wake up and before you go to bed. Rinsing your mouth with water after consuming meals is another great way to ensure bacteria and plaque do not build up in your mouth. If plaque does build up, we recommend a professional teeth cleaning from one of our amazing dentists to put you back on the right track!

Arestin Thousand Oaks

Periodontal disease is a serious infection under your gum line.

ARESTIN® (minocycline hydrochloride) is a powerful antibiotic used to kill bacteria in your gum line.
  • It’s placed directly in the infected areas—or “pockets”—in your gums.
  • It’s applied right after scaling and root planing, the dental procedure that disrupts stubborn plaque and bacteria below your gum line—where brushing and flossing can’t reach.
ARESTIN® starts working quickly, right at the source of infection, and keeps fighting bacteria long after you leave the dental office. 1,2 ARESTIN® fights infection and inflammation for 30 days,2 and provides significantly better results than scaling and root planing alone for up to 90 days.3
