Services & Treatments

Preventive Care

Dr. Mello-Anderson approaches preventive care as the foundation of every child's long-term oral health. She conducts routine dental exams and uses digital X-rays to monitor tooth development and catch issues early. She provides hands-on guidance for children and parents on brushing technique, flossing, and dietary choices that protect teeth. When exam findings suggest future orthodontic concerns, she coordinates timely referrals. The goal is not just a healthy checkup today but lifelong habits that prevent problems before they start.

Routine Cleaning

Dr. Mello-Anderson recommends most children visit every six months for a professional cleaning. During each appointment, plaque and calculus are removed from tooth surfaces using both manual and electric or ultrasonic scalers, reaching areas that daily brushing misses. The visit is designed to be comfortable and low-pressure, particularly for younger children and first-time patients. Each cleaning ends with polished, smooth teeth and a quick review of at-home hygiene habits to reinforce what children can do between visits.

Tools used here

Manual and electric/ultrasonic scalersManual scalers are precision hand instruments used to remove plaque and calculus from tooth surfaces and just below the gumline, while electric or ultrasonic scalers use high-frequency vibration to break up stubborn buildup more quickly and gently. Using both types allows the cleaning to be thorough and matched to each child's specific needs and sensitivity level.

Digital X-rays

Dr. Mello-Anderson uses digital X-rays to see what cannot be detected during a visual exam alone. Depending on a child's age and clinical needs, she may take bitewing, periapical, panoramic, occlusal, or orthodontic images. Digital technology reduces radiation exposure significantly compared to traditional film and delivers results instantly on screen. X-rays help her detect cavities between teeth, track erupting permanent teeth, evaluate jaw injuries, and plan appropriate referrals. Most children have X-rays taken once per year as a preventive measure.

Fluoride Treatment

Dr. Mello-Anderson offers professional fluoride treatments as a fast and proven way to protect children's teeth from decay. A concentrated fluoride paste is applied to tooth surfaces and left in place for several minutes. Research shows fluoride can reduce the risk of cavities by up to 70 percent. After treatment, children are asked to avoid eating, drinking, or rinsing for at least 30 minutes to allow full absorption. The application is painless and adds only minutes to a routine checkup visit.

Dental Sealants

Dr. Mello-Anderson applies dental sealants to protect the deep grooves of back teeth, where most childhood cavities begin. The process involves cleaning the tooth, applying an acidic gel to improve bonding, rinsing, painting on a thin sealant coating, and hardening it with a special blue light. The entire application is quick and painless. Sealants create a physical barrier against cavity-causing bacteria and typically last a few years. They are among the most effective preventive tools available for school-age children.

Tools used here

Sealant material
Blue light sealant hardening equipmentA focused blue curing light is directed at freshly applied sealant material on tooth surfaces, triggering a rapid chemical reaction that hardens the protective coating in seconds. This instant hardening locks the sealant into the deep grooves of the tooth before the child leaves the chair, requiring no waiting period and keeping the process fast and comfortable.

Fillings

When a child develops a cavity or suffers a cracked tooth, Dr. Mello-Anderson removes the damaged tissue and restores the tooth with a filling. She places tooth-colored composite resin fillings that blend naturally with surrounding enamel, or silver-colored amalgam fillings where durability is the priority. Dr. Mello-Anderson uses behavior management techniques alongside treatment to help children stay calm and comfortable throughout the procedure, making the experience as smooth as possible for both the child and the parent.

Tooth Extractions

When a tooth cannot be saved, Dr. Mello-Anderson recommends extraction as the most direct path to restoring the child's oral health. Extractions may be needed for teeth severely damaged by decay, impacted teeth, those with delayed natural shedding, or teeth causing complications after trauma. Dr. Mello-Anderson prioritizes comfort throughout and may recommend nitrous oxide for anxious patients. Clear pre- and post-procedure guidance helps parents manage the recovery and understand what to expect in the days following the appointment.

Nitrous Oxide Sedation

Dr. Mello-Anderson offers nitrous oxide, commonly called laughing gas, for children who experience dental anxiety, have a strong gag reflex, or are sensitive to sounds and sensations during dental procedures. A small nosepiece delivers a carefully controlled mix of nitrous oxide and oxygen, allowing the child to remain fully awake and responsive while feeling calm and relaxed. Effects begin within minutes and wear off completely once the child breathes pure oxygen after the nosepiece is removed. No recovery time is needed.

General Anesthesia

For young children who cannot safely receive care while awake, or for children with special health needs requiring extended procedures, Dr. Mello-Anderson can arrange treatment under general anesthesia. The child is fully asleep and unaware throughout the appointment, allowing necessary dental work to be completed safely in a single visit. General anesthesia is recommended on a case-by-case basis following a thorough clinical evaluation and is reserved for situations where other sedation options are not sufficient.

Special Needs Dental Care

Dr. Mello-Anderson has specialized training in providing dental care to children with physical, developmental, mental, sensory, behavioral, cognitive, and emotional conditions. She adapts her communication style, pacing, clinical technique, and environmental accommodations to each child's specific needs. Rather than applying a standard protocol, she and the team at Associated Pediatric Dentistry build individualized treatment plans that account for each child's unique health profile. When procedures require it, sedation and general anesthesia options ensure children with complex needs receive complete, safe care.

Emergency Dental Care

Dental emergencies rarely happen at convenient times. Dr. Mello-Anderson is part of Associated Pediatric Dentistry's on-call system, ensuring a dentist is available outside of normal office hours when urgent situations arise. The emergency line handles toothaches, knocked-out permanent teeth, cuts to the lip or tongue, and other acute issues. When a parent calls, they receive immediate guidance on assessing the injury and steps to take before arriving at the office, reducing anxiety and preventing further damage.

Frequently Asked Questions

Does Dr. Mello-Anderson accept my dental insurance?
Associated Pediatric Dentistry's insurance participation details are not publicly available. To confirm whether your specific plan is accepted and whether the practice will file claims on your behalf, contact the O'Fallon office directly at (618) 622-0212 or email [email protected]. Bringing your insurance card to the first visit will help the front desk team verify your benefits before treatment begins.
How does Dr. Mello-Anderson help children who are nervous about dental visits?
Dr. Mello-Anderson works within a practice philosophy that dental visits should not feel scary. Associated Pediatric Dentistry is known for a playful, distraction-based approach where the team uses engaging interactions to build trust with nervous children before and during treatment. For children whose anxiety is more significant, Dr. Mello-Anderson offers nitrous oxide sedation, which keeps children calm and comfortable while they remain fully awake and responsive throughout the procedure.
When should my child have their first dental appointment?
The American Academy of Pediatric Dentistry recommends that children visit a pediatric dentist by age one or within six months of the first tooth erupting. An early visit with Dr. Mello-Anderson at Associated Pediatric Dentistry allows her to assess eruption patterns, identify early decay, and give parents practical guidance on feeding habits, teething, and age-appropriate oral hygiene routines before problems have a chance to develop.
My child has a developmental disability. Can Dr. Mello-Anderson treat them?
Yes. Dr. Mello-Anderson has specialized training in caring for children with physical, developmental, cognitive, sensory, behavioral, and emotional conditions. She adapts her clinical approach and communication style to each child's specific needs. When a procedure requires it, general anesthesia can be arranged so that children with complex healthcare needs receive thorough, safe dental care in a single appointment without distress.
Can my child be seen at any Associated Pediatric Dentistry location?
Yes. Associated Pediatric Dentistry's four locations in O'Fallon, Belleville, Glen Carbon, and Mount Vernon share synchronized patient records. Dr. Mello-Anderson or any dentist on the team can access your child's complete dental history regardless of which office you visit. Families can schedule at whichever location is most convenient, whether that changes from appointment to appointment or stays consistent.
Does my child need dental sealants?
Dental sealants are thin protective coatings applied to the chewing surfaces of back teeth, where the majority of childhood cavities develop. Dr. Mello-Anderson applies sealants in a quick, painless process and uses a special blue light to harden the material in seconds. Sealants are typically recommended after permanent molars erupt and can provide years of cavity protection. They are one of the most cost-effective preventive treatments available for school-age children.
What should I do if my child has a dental emergency after office hours?
Call Associated Pediatric Dentistry at (618) 622-0212. The practice maintains an after-hours emergency line with a dentist on call at all times. Whether your child has knocked out a permanent tooth, is experiencing a severe toothache, has a cut to the lip or tongue, or is dealing with another urgent dental issue, the on-call dentist will provide immediate guidance and, when necessary, arrange an emergency appointment.

Why a specialist

Why see a pediatric dentist?

Pediatric dentists like Dr. Mello-Anderson complete two additional years of residency training beyond dental school, focusing exclusively on children's dental development, behavior guidance, and care for patients with complex medical, developmental, or sensory needs. A general dentist sees patients of all ages but may not have the same depth of training in recognizing subtle growth milestones, managing dental anxiety in young children, or adapting care for children with disabilities or chronic conditions. Catching problems such as crowding, eruption delays, or early-stage decay is far more effective before they progress. Dr. Mello-Anderson and her colleagues at Associated Pediatric Dentistry also offer sedation options, including nitrous oxide and general anesthesia, that many general dental offices cannot provide. For children who need more than routine care, this level of specialized training and clinical capability often determines whether treatment is possible at all.
