    PEDIATRIC DENTISTRY

    • Dental Exam & Cleaning (Prophylaxis)

    Preventative care is a foundation of dentistry. The American Academy of Pediatric Dentistry recommends visiting your pediatric dentist regularly every six months for cleanings, examinations, and consultations for potential treatment. If your child has special needs or is more predisposed to dental caries, the dentist may recommend more frequent visits to more closely manage your child’s oral health. After the cleaning, fluoride will be applied to the teeth to help protect and strengthen the weak areas against decay. As a routine patient that visits the pediatric dentist at least twice a year, you will have the opportunity to discuss your child’s dental health with the doctor and answer any questions you may have. At Sunny Smiles, we believe that the relationship between the dental staff and the patient is of utmost importance.

    • X-Rays (Radiographs)

    In general, children need X-rays more often than adults. Their mouths grow and change rapidly. X-rays can often show weaknesses in the tooth structure (such as demineralization) that may not be visible with the naked eye. The American Academy of Pediatric Dentistry recommends X-ray examinations every six months for children with a high risk of tooth decay. Children with a low risk of tooth decay require X-rays less frequently. We use digital radiography which uses approximately 1/4 the radiation of the traditional dental x-rays.

    • Fluoride

    Fluoride is a naturally occurring element that has been shown to help strengthen teeth in children and also prevent decay in people of all ages. Topical fluoride, in particular is helpful for promoting oral health. Depending on your child’s oral health, the doctor may recommend a fluoride treatment every 3, 6, or 12 months. Along with monitoring the development of your child’s teeth, a fluoride supplementation may be prescribed.

    • Sealants

    Dental sealants are clear coatings applied to the surfaces of a child’s molars to prevent the development of tooth decay. They work by preventing food and plaque from resting in the grooves and crevices of molars – an area especially susceptible to cavities.

    • Tooth Colored Fillings (Composite Resin)

    Your child may need a dental filling if he or she has cavities. Though some cavities are obvious and cause pain, many are not visible to eye and asymptomatic. That is why all children should visit a pediatric dentist twice yearly for a professional dental exam. Regular exams can identify tooth decay in earliest phases, when it is most easily treated. .

    • Pulp Treatment (Pulpotomy)

    Pulp therapy (pulpotomy) is the treatment of infected nerves and blood vessels in teeth. Pulp therapy generally becomes necessary for two reasons: either as a result of extensive tooth decay (dental cavities) or as the result of tooth injury. Failure to provide the necessary pulp therapy could result in your child experiencing pain, infection, swelling, or loss of the tooth.

    • Stainless Steel Crowns (SSCs)

    Stainless steel crowns are used to restore back teeth that are too badly decayed to hold tooth colored fillings. When tooth decay on back teeth has been left untreated, teeth may have extensive damage to the enamel, dentin and sometimes the nerve (pulp). In such cases, tooth-colored fillings are not a viable option which makes stainless steel crowns necessary. These prefabricated silver-colored crowns are fitted to the patient’s tooth and then cemented to prevent further damage until these teeth fall out naturally with the crowns on them.

    • Silver Diamine Fluoride

    Silver Diamine Fluoride is an FDA-Approved antimicrobial liquid that is able to treat cavities in a non-invasive, fast, affordable, and painless manner. It is a liquid that is simply brushed on to the cavity that can stop current decay and also prevent new decay in the future. Silver Diamine Fluoride application does not replace the need for regular fillings and crowns although it is effective in preventing further decay.

    • Extractions (Tooth Removal)

    Extractions are done only as a last resort in the case of severe tooth decay. If a primary molar is removed prematurely, a space maintainer will be placed. Primary teeth are essential in maintaining the natural spacing in your child’s jaw for the permanent teeth. Extractions are needed for grossly decayed teeth, infections, problems with wisdom teeth and orthodontic reasons to help facilitate tooth alignment when crowded teeth are present.

    • Space Maintainers

    Space maintainers are used when a primary tooth has been prematurely lost, or extracted, to hold space for the developing permanent tooth. If space is not maintained, teeth on either side of the extraction site can drift into the space and prevent the permanent tooth from erupting into its proper position. The space maintainer will be removed from your child’s mouth once his/her permanent tooth replacing the extracted tooth comes in.

    • Mouthguards

    Mouth guards are used to protect the natural teeth, dental restorations and gums from damage caused by contact sports or activities that pose a risk to the teeth. If your child participates in any kind of contact sport, the American Dental Association recommends that they wear a mouthguard.

    SEDATION DENTISTRY

    • Nitrous Oxide (Laughing Gas)

    The American Academy of Pediatric Dentistry (AAPD) recognizes nitrous oxide/oxygen inhalation as a safe and effective technique to reduce anxiety, produce analgesia, and enhance effective communication between your child and your dentist.

    • General Anesthesia

    General anesthesia is a type of sedation that generally takes place under the care of a professionally trained anesthesiologist, separate from the dentist performing the dental procedure. The child will be completely asleep the entire time, and will feel no pain.

    COSMETIC DENTISTRY

    • Invisalign

    Invisalign is an orthodontic treatment offered to adolescents that uses a series of clear, custom-made, BPA-free plastic aligners to straighten your child’s teeth.

    They are made of smooth and virtually invisible plastic, so, unlike traditional braces, there are no metal brackets to attach and no wires to tighten. The aligners gradually and gently shift teeth into the proper position, based on the exact movements that your dentist plans out.

    • Teeth Whitening

    Teeth whitening procedures are used to brighten the appearance of your smile – Sometimes by as many as 5 to 10 shades in a single session. Professional teeth whitening services can be performed in an office setting or prescribed for take-home use by a patient. In comparison to over-the-counter teeth whitening treatments, professional whitening uses stronger whitening agents that deliver faster and more effective results.

    • ICON

    ICON resin infiltration is used to treat the white spots left behind on teeth after braces are removed. It can also treat developmental defects on teeth, such as white spots or “freckles” that appear on some teeth. These post-braces spots or developmental blemishes are inherently weaker than a healthy tooth, and many patients dislike how they look.

    ICON is a resin material that penetrates the white spots or defects to make them stronger. In doing so, the blemishes reflect light in a manner similar to a healthy tooth, making the blemishes less noticeable. The application of ICON is painless, non-invasive, and requires no local anesthesia. Relative to other cosmetic options like veneers, ICON is also much more affordable. The results can vary and there is no guarantee the blemishes will be completely unnoticeable following treatment with ICON. However, the vast majority of our patients are highly satisfied with the outcome.

    EMERGENCY DENTAL SERVICES

    Although dental injuries and dental emergencies are often distressing for both children and parents, they are also extremely common. Approximately one third of children have experienced some type of dental trauma, and more have experienced a dental emergency. There are two peak risk periods for dental trauma with the first being the toddler years (18-40 Months) when environmental exploration begins, and the second being the adolescent period, when sporting injuries become commonplace.

    Complimentary First Birthday Checkup

    Sunny Smiles Pediatric Dentistry believes that prevention is better than cure, which is why we are strong advocates of starting your child’s dental visits by their first birthday.

    Both the American Academy of Pediatric Dentistry and the American Dental Association say that the first dental visit should occur within six months after the baby’s first tooth appears, but no later than the child’s first birthday.

    We were very happy with the care we received at Sunny Smiles. Dr. Yashi and her staff were excellent! The office was very clean, we did not wait long to be seen, & the process of being a new patient was very easy. Dr. Yashi took the time to explain everything in detail, which was very much appreciated. Not only did she provide a thorough explanation of the treatment plan, but she also provided very helpful advice on helping a child be comfortable at the dentist. Highly recommend!

    Matthew S.

    I am SOO HAPPY my kids switched to Sunny Smiles Pediatric Dentistry. Dr. Yashi is so thorough during the cleaning and exam. She really takes her time to explain what the kids need to be doing to have healthy teeth. The staff is super kid friendly and even my nervous 6 year old LOVED IT. There was no wait and we were seen immediately at the time of our appointment (kind of a bummer for the kids since they have video games in the waiting room).

    Sunho C.

    This was my son’s first time with Dr. Yashi at Sunny Smiles and we are very happy. The knowledge of her, the patience, the kindness of her, we did not have to wait too long, the staff is also friendly and professional. I am very happy to find this place for my little one.
