Sioux City Dentist Offers Painless No-Drill Fillings


Do you dread the drill? Wince at the whine? Shrink from shots? Then you will be happy to know that Sioux City dentist, Dr. Dona Prince, repairs cavities with laser technology. Her fillings look natural, and last many years, with good oral habits. Best of all, no drilling is needed!

How cavities occur

You might be surprised to learn that sugar does not directly cause tooth decay. Acid erosion causes holes in tooth enamel. However, those acids are produced as a by-product of oral bacteria thriving on sugars and starches, trapped in a tacky biofilm of plaque. The condition is called tooth decay, and the result is a cavity. The body tries to naturally repair initial tiny openings in enamel with fluoride and other minerals from saliva. If plaque isn’t removed regularly with good brushing and flossing habits, though, bacteria continue to dissolve tooth structure. Eventually, dental caries can infect the nerve center of the tooth, requiring extraction.

Laser prep

Drilling is the conventional process of removing diseased tooth structure so that a filling can be placed. A bur at the end of a motorized handpiece grinds it away. Drilling causes vibration and frictional heat, and it takes a bit of time. That’s why numbing is necessary. Laser preparation avoids all these common discomforts.

A dental hard tissue laser essentially vaporizes damaged tooth structure with an intense beam of light. Because energy is precisely directed, the technique is fast, and healthy tooth is spared. The system is quiet, too. There is little chance that decay will develop under a laser-prepped filling, because the laser efficiently and effectively kills bacteria in the cavity.

Composite fillings

Historically, amalgam was the go-to material for dental fillings. While some dentists still place these silver-colored restorations, Dr. Prince suggests the lovely appearance and durability of composite resin material. Modern cosmetic fillings are strong enough even for molar restorations. They resist staining, and blend beautifully with your smile.
