Cleanings & Prevention
What do sealants involve?
Sealants are easily applied by your dentist or dental hygienist and the process takes only a couple of minutes per tooth.
The teeth to be sealed are thoroughly cleaned and then surrounded with cotton to keep the area dry. A special solution is applied to the enamel surface to help the sealant bond to the teeth. The teeth are then rinsed and dried. Sealant material is carefully painted onto the enamel surface to cover the deep grooves or depressions. Depending on the type of sealant used, the material will either harden automatically or with a special curing light.
Proper home care, a balanced diet, and regular dental visits will aid in the life of your new sealants.
Are dental x-rays safe?
We are all exposed to natural radiation in our environment. The amount of radiation exposure from a full mouth series of x-rays is equal to the amount a person receives in a single day from natural sources.
Dental x-rays produce a low level of radiation and are considered safe. Dentists take necessary precautions to limit the patient’s exposure to radiation when taking dental x-rays. These precautions include using lead apron shields to protect the body and using digital radiographs that greatly reduces the exposure time of each x-ray.
How often should dental x-rays be taken?
The need for dental x-rays depends on each patient’s individual dental health needs. Your dentist and dental hygienist will recommend necessary x-rays based on the review of your medical and dental history, dental exam, signs and symptoms, age consideration, and risk for disease.
A full mouth series of dental x-rays is recommended for new patients. A full series is usually good for three to five years. Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems. Panoramic radiographs are recommended to give an overview of the jaws, and are particularly useful when examining wisdom teeth or the developing teeth.
When should I take my child to the dentist for the first time?
It’s important to get an early start on dental care, so that your child will learn that visiting the dentist is a regular part of health care. The first step is to choose a dentist for your child.
It may be your own dentist or one who specializes in treating children (called a pediatric dentist). Once you have selected a dentist, call the office to find out at what age he or she prefers to see child patients for the first time. CDA encourages the assessment of infants, by a dentist, within 6 months of the eruption of the first tooth or by one year of age.
It’s important to make the first visit a positive experience for your child – one reason why it’s best to visit before a problem develops. If you think there is a problem, however, take your child to the dentist right away, no matter what age.
If you are a nervous dental patient, ask your spouse or another family member to take the child for the appointment. If your child senses that you are nervous, he or she may feel nervous too. When you talk to your child about going to the dentist, explain what will happen without adding things like “it won’t hurt” or “don’t be scared.”
Be sure to get an early start on regular dental care at home. Start cleaning your child’s mouth with a soft damp cloth before teeth come in and continue with a soft toothbrush once he or she has a first tooth. Limit the number of sugary treats you give your child, and focus on healthy food choices from the very beginning.
How does gum disease get started?
Gum disease begins when plaque adheres at and below the visible edge of your gums. If plaque is not removed every day by brushing and flossing, it hardens into tartar (also called calculus). Tartar promotes a bacterial infection at the point of attachment. In these early stages, gum disease is called gingivitis.
Your gums may be a bit red, but you may not notice anything. As gingivitis gets more serious, tiny pockets of infection form. Your gums may be puffy and may bleed a little when you brush, but it is not painful. Over time, the infection destroys the gum tissue. Eventually, you may be at risk of losing one or more teeth.
How can I prevent gum disease?
Prevention is the most important factor in the fight against gum disease. It is essential to keep your teeth and gums clean. Brush your teeth properly at least twice a day and floss at least once every 24 hours.
Using proper brushing and flossing techniques is equally important. Be sure to see your dentist regularly for professional cleaning and dental exams, so that he or she can detect any early signs of gum disease, and provide appropriate treatment.
What if I am already in the early stages of gum disease?
If you have gum disease, getting rid of plaque and tartar gives your gums a chance to get better. That’s why in the early stages of gum disease, the best treatment is:
Cleaning by your dentist or dental hygienist to remove built-up tartar, brushing twice a day to remove plaque and flossing once a day to remove plaque.
When gum disease is more serious, your dentist may refer you to a dental specialist called a periodontist. A periodontist has a least three years of extra university training in treating gum disease, and in restoring (or regenerating) bone and gum tissue that have been lost because of gum disease.
A periodontist also treats serious forms of gum disease that do not get better with normal dental care. When serious gum disease is found, brushing and flossing become even more important.
Should I be using fluoridated toothpaste with my child?
For children from birth to 3 years of age, the use of fluoridated toothpaste is determined by the level of risk of tooth decay. Parents should consult a health professional to determine whether their child up to 3 years of age is at risk of developing tooth decay. If such a risk exists, the child’s teeth should be brushed by an adult using a minimal amount (a portion the size of a grain of rice) of fluoridated toothpaste. Use of fluoridated toothpaste in a small amount has been determined to achieve a balance between the benefits of fluoride and the risk of developing fluorosis. If the child is not considered to be at risk, the teeth should be brushed by an adult using a toothbrush moistened only with water.
For children from 3 to 6 years of age, only a small amount (a portion the size of a green pea) of fluoridated toothpaste should be used. Children in this age group should be assisted by an adult in brushing their teeth.
Why do young children need to be assisted or supervised with tooth brushing?
Young children tend to swallow toothpaste when they are brushing, which may increase their exposure to fluoride and contribute to dental fluorosis. For this reason, children need to be assisted or supervised with tooth brushing. An adult needs to ensure that an appropriate amount of toothpaste is used, that the child spits out the toothpaste rather than swallows it, and that the teeth are cleaned effectively.
General & Cosmetic Dentistry
Do porcelain veneers stain with normal things like tea, coffee or wine?
Porcelain veneers should never stain, however if your teeth have a propensity to stain you should try to avoid or minimize the behaviors that lead to staining, and look after them as recommended above with normal hygiene and maintenance procedures.
What does tooth whitening involve?
This type of tooth whitening usually requires two visits. At the first appointment, impressions (molds) will be made of your teeth to fabricate custom, clear plastic, trays.
At your second appointment, you will try on the trays for proper fit, and adjustments will be made if necessary. The trays are worn with special whitening solution either twice a day for 30 minutes or overnight for a couple of weeks depending on the degree of staining and desired level of whitening. It is normal to experience tooth sensitivity during the time you are whitening your teeth, but it will subside shortly after you have stopped bleaching.
You will receive care instructions for your teeth and trays, and be encouraged to visit your dentist regularly to help maintain a beautiful, healthy, white smile.
What does getting porcelain veneers involve?
Getting veneers usually requires two visits to complete the process, with little or no anesthesia required during the procedure. The teeth are prepared by lightly buffing and shaping the surface to allow for the thickness of the veneer. A mold or impression of the teeth is taken and a shade (color) will then be chosen by you and the dentist.
On the second visit the teeth will be cleansed with special liquids to achieve a durable bond. Bonding cement is then placed between the tooth and veneer and a special light beam is used to harden and set the bond.
You will receive care instructions for veneers. Proper brushing, flossing and regular dental visits will aid in the life of your new veneers.
What happens to my teeth after veneers, and will I ever get cavities?
The integrity of veneered teeth is only marginally compromised, and the veneer is bonded to the existing teeth. There is no higher incidence of decay provided that the veneers are properly cared for as detailed above, regular brushing with toothpaste, and flossing. Keep your sugar consumption low and confined to meal times, good dental advice generally to prevent decay.
What does getting a crown involve?
A crown procedure usually requires two appointments. Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown. A mold will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.
While the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite is accurate.
You will be given care instructions and encouraged to have regular dental visits to check your new crown.
How are composite fillings placed?
Composite fillings are usually placed in one appointment. While the tooth is numb, your dentist will remove decay as necessary. The space will then be thoroughly cleaned and carefully prepared before the new filling is placed. If the decay was near the nerve of the tooth, a special medication will be applied for added protection. The composite filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function.
It is normal to experience sensitivity to hot and cold when composite fillings are first placed, however this will subside shortly after your tooth acclimates to the new filling.
You will be given care instructions at the conclusion of your treatment. Good oral hygiene practices, eating habits, and regular dental visits will aid in the life of your new fillings.
My dentist is recommending an amalgam filling but I want a white filling (or vice versa). Where does this leave me?
You and your dentist should decide together which filling material will work best for you. If you want one kind of material or wish to avoid a certain type, tell your dentist. He or she will advise you if the material that you want will work.
The most common materials for restoring (or filling) teeth are amalgam (sometimes called silver), composite resin (sometimes called plastic or white), gold, ceramic and glass ionomer. Each material has pros and cons. Some materials may better meet your needs than others.
It depends on the size of your cavity and its location. If your cavity is in a molar, for example, the filling will receive a lot of biting force or stress, so a strong material is needed. If it is in the front of your mouth where there is less biting force and people will see it, a different material may be better.
What’s the difference between the bleaching I can do at home with a kit from the store and the bleaching that my dentist does?
Dentists have been doing what’s called “non-vital” bleaching for many years. Non-vital bleaching is done on a damaged, darkened tooth that has had root canal treatment. “Vital” bleaching is done on healthy teeth and has become more popular in recent years.
Vital bleaching, also called whitening, may be carried out in the dental office or the dentist may instruct the patient on how to do the bleaching at home. There is also a wide variety of products for sale in stores. Not all products are the same and not all give you the same results.
Different products, including those used by dentists, may also have different risks and side effects.
Here is an overview:
Whitening toothpastes with abrasive ingredients are really not bleaching products at all, but work on surface stain only. These products are sold in many stores.
Some whitening toothpastes do contain a chemical ingredient (or “bleach”) that causes a chemical reaction to lighten teeth. Generally, they have the lowest amount of “bleach.” They may not whiten as well as stronger products, but they have less chance of side effects. These pastes are brushed onto teeth and rinsed off, like regular toothpaste.
Bleaching kits sold in stores stay on your teeth longer than toothpaste and contain stronger bleach.” These store-bought products do not come with the added safety of having your dentist monitor any side effects. They also come with a one-size-fits-all tray that holds the “bleach” and is more likely to leak the chemical into your mouth.
Dentists may use products with stronger “bleach”, but they give patients careful instructions to follow. They are also trained to spot and treat the side effects that patients sometimes report during bleaching. In addition, if a tray is needed to apply the “bleach”, dentists supply custom-made trays. Because products used by dentists are strong, they tend to produce the best results.
Patients should be aware that the long-term use of whitening or bleaching products may cause tooth sensitivity or tooth abrasion. Please consult with your dentist before using a whitening or bleaching product.
Is Nitrous Oxide Safe?
Nitrous oxide is very safe, because it’s easy to take and mild. Nitrous oxide is not addictive. While inhaling nitrous oxide, you remain fully conscience and aware of your surroundings. After coming off of the gas, the effects of it are gone.
If you have respiratory problems or other breathing problems, such as asthma, you should talk with your dentist to see if you are a candidate for nitrous oxide.
