A Reason to smile

It's different for kids.

Excellent pediatric dental care requires the perfect blend of skilled precision and gentle touch.

Welcome to Small World Children's Dentistry. Here, kids rule. (And often drool!)

We pride ourselves on the comprehensive oral health of children from infancy through teenage years. But its more than just oral health. It's intuitive understanding and connection that our doctors and staff share with patients and parents. It starts with listening. And it doesn't stop until every child in our care is properly and professionally treated. And smiling! Oh, and we've been known to make a parent or two smile as well! 

We'd love to learn more about you and your child. Answer your questions. Or schedule an appointment at either our Pewaukee or Brookfield office.

Thank you!


Restorative Dentistry

Tooth Colored Fillings- 

We use a resin tooth-colored filling to restore the natural shape and structure of the tooth. 


Extractions may be necessary due to Abscess, severe decay, trauma, or orthodontic needs. 

Space Maintenace

In order to prevent shifting and loss of space, space maintainers are placed in the area the primary tooth was extracted. This is to hold the space for the adult tooth to erupt in a more appropriate position.


If your child’s cavity is too large to restore with a tooth-colored filling, a crown may be recommended. Crowns help protect and support the tooth, preventing further cavities and breakdowns from occurring. 

Nerve Treatment-

The pulp of a tooth is the inner, central core of the tooth. A pulpotomy removes the diseased pulp tissue within the crown portion of the tooth. Next, a medicament is placed to prevent bacterial growth and to calm the remaining nerve tissue. This is followed by a final restoration (usually a stainless steel crown).

Preventative Dentistry
The American Academy of Pediatric Dentistry recommends that your child sees a dentist every six months. 
Fluoride is a naturally occurring element, which has shown to prevent tooth decay by as much as 50-70%. It also helps repair weakened enamel before cavities form.
Radiographs allow dentists to diagnose and treat cavities that cannot be detected during a clinical examination. The American Academy of Pediatric Dentistry recommends radiographs once a year. However, for children with high risk carries every six months.


A sealant is a resin material usually applied to the chewing surfaces of molars. It acts as a barrier that prevents bacterial plaque from entering into the pits and grooves. Sealing a tooth is fast and painless, can last several years before needing to be reapplied. Sealants have been shown to reduce cavities by 70%

Infant care

The average infant starts seeing a dentist at age 18 months; however, this can vary per child. This is the optimal time to ask questions about your child’s mouth and teeth. We will do a complete oral exam to check growth and development, oral hygiene, bite, as well as clean your child’s teeth.

Dental Emergency

24 hour on call 

When an emergency occurs, it is important to seek treatment as soon as possible. 

  • Dental Abscesses / Facial Swelling

  • Severe Toothaches / Pain

  • Chipped teeth

  • Displacement Baby / Permanent tooth 

  • Injury to the jaw

Nitrous Oxide

(Laughing Gas)

Some children are given nitrous oxide/oxygen to relax them for their dental treatment. Nitrous oxide is administered through a small breathing mask which is placed over the child’s nose, allowing them to relax without putting them to sleep. The American Academy of Pediatric Dentistry recognizes this technique as a very safe, effective technique for treating children’s dental needs. The gas is mild, easily taken, and it is quickly eliminated from the body. While inhaling nitrous oxide/oxygen, your child remains fully conscious. 

Special Needs Dentistry


The American Academy of Pediatric Dentistry defines special healthcare needs as “any physical, developmental, mental, sensory, behavioral, cognitive, or emotional impairment or limiting condition that requires medical management, healthcare intervention, and use of specialized services or programs.” Whether your child’s condition is congenital, developmental, or the result of disease or trauma, we can provide guidance and raise awareness of their special dental care needs.

IV Sedation 

Most dental procedures in children are completed with Nitrous Oxide/ Local Anesthesia; however, very young, fearful or uncooperative children may require sedation. Intravenous (IV) sedation is a deep sleep that insulates your child from the stress and discomfort associated with dental procedures.

Oral Hygiene Habits


Many infants / young children like to suck their thumbs, fingers, or pacifiers. However, sucking habits can cause problems as your child's teeth and mouth develop, like crooked teeth and changes to the shape of their face and mouth. Children should stop using a pacifier by age 3.

Here are a few tips to help them to stop:

Instead of scolding your child for sucking, praise them for not sucking.
