Documented experience
Dr. Gerusa Mello-Anderson is a pediatric dentist at Associated Pediatric Dentistry, serving families across Southern Illinois from office locations in O'Fallon, Belleville, Glen Carbon, and Mount Vernon. Pediatric dentists complete two additional years of residency training beyond dental school, giving Dr. Mello-Anderson focused expertise in child dental development, behavior guidance, and adapted care for children with physical, developmental, sensory, behavioral, or cognitive conditions. She provides the full range of childhood dental services, from routine exams, cleanings, fluoride treatments, and sealants to fillings, extractions, and urgent after-hours care. For children who struggle with dental anxiety or require extended treatment, Dr. Mello-Anderson offers nitrous oxide sedation and, when clinically appropriate, general anesthesia. This allows children with special healthcare needs to receive the care they need safely and comfortably. Associated Pediatric Dentistry has served Metro East communities since 1979, and Dr. Mello-Anderson practices as part of a six-dentist team with synchronized records across all four locations, so families can access consistent, high-quality care at whichever office is most convenient.
“We create a fun and safe environment where all children can have their dental needs met, helping children create healthy dental habits that will last a lifetime.”

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.

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.

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.

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.

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.

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.

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.
Tools used here
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.
Tools used here
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.
Tools used here
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.
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.

Why a specialist
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.
