Sugar Is the Only Thing That Causes Cavities
While sugar is a major contributor to tooth decay, it is not the only culprit. Cavities form when bacteria in your mouth feed on carbohydrates and produce acid that erodes enamel. Starchy foods like bread, crackers, and chips can be just as harmful because they break down into sugars that feed these bacteria. Acidic foods and beverages can also weaken enamel directly. A balanced diet combined with good oral hygiene is the best defense against decay.
Brushing Harder Cleans Better
Many people believe that applying more pressure while brushing leads to cleaner teeth. In reality, brushing too hard can damage enamel and irritate gum tissue, leading to recession and sensitivity. A soft-bristled toothbrush used with gentle, circular motions is far more effective at removing plaque without causing harm. If your toothbrush bristles are fraying within a few weeks, you are likely brushing with too much force.
You Only Need to See a Dentist When Something Hurts
This is one of the most dangerous dental myths. Many oral health problems, including cavities, gum disease, and even oral cancer, can develop without any noticeable symptoms in their early stages. Regular dental checkups allow your dentist to detect these issues before they become painful or require complex treatment. Preventive visits at Stephen Cheung DDS are designed to keep small problems from becoming big ones.
Baby Teeth Don't Matter Because They Fall Out
Primary teeth play a critical role in a child's development. They guide the permanent teeth into their correct positions, aid in speech development, and allow children to chew properly. Neglecting baby teeth can lead to infections, premature tooth loss, and orthodontic problems later in life. Establishing good oral hygiene habits early and scheduling regular dental visits for your child sets the foundation for a lifetime of healthy smiles.
Whitening Weakens Your Teeth
Professional teeth whitening, when performed under the supervision of a qualified dentist, does not weaken tooth structure. The bleaching agents temporarily open the pores of the enamel to lift stains, and the teeth remineralize naturally afterward. Over-the-counter products used excessively or incorrectly can cause sensitivity, but professionally supervised whitening at our Lodi office is both safe and effective.
