Dental answers, made clearer
Clear, concise answers to common dental questions—written for people who want the essential information first.
Children often mouth breathe due to blocked nasal passages from allergies, enlarged tonsils, or adenoids, rather than by choice. Persistent mouth breathing during growth years can contribute to a narrower jaw, dry mouth, and a higher risk of crowded or misaligned teeth.
Read the answerYes, it's common for permanent teeth to initially erupt at odd angles or with gaps, especially before the jaw finishes growing, and many of these cases improve naturally. A dentist can advise during routine checkups whether the pattern is expected to self-correct or needs orthodontic attention.
Read the answerNo, brushing harder doesn't remove more plaque; it mainly wears down enamel and irritates the gums, which can lead to sensitivity and recession over time. Gentle brushing with a soft-bristled brush for two minutes, twice a day, is more effective at removing plaque without damaging tooth or gum tissue.
Read the answerScaling and polishing is generally not painful, though patients with sensitive teeth or inflamed gums may feel some mild discomfort during the deeper cleaning around the gumline. Any pressure sensation typically fades quickly once the cleaning is done.
Read the answerA routine scaling and polishing session usually takes around 30 to 45 minutes, though it can take longer if there's significant tartar buildup. Sessions combined with a full checkup or X-rays will naturally take a bit more time.
Read the answerScaling removes hardened plaque and tartar from the tooth surface and along the gumline using fine instruments, while polishing smooths the enamel afterward to remove surface stains and make it harder for new plaque to stick. They're done together as one combined cleaning procedure, not as separate treatments.
Read the answerNo, when performed by a dentist at the recommended interval, scaling and polishing doesn't damage healthy enamel. The confusion often comes from a temporary rough or sensitive feeling afterward, which is normal and settles within a day or two, not a sign of harm.
Read the answerTeeth can feel unusually smooth or oddly rough right after scaling simply because the layer of tartar that had built up on the surface has been removed, exposing the natural tooth texture underneath. This sensation is temporary and isn't a sign that anything went wrong.
Read the answerSmoking restricts blood flow to the gums, which weakens the tissue's ability to fight infection and heal, making smokers significantly more prone to gum disease and slower recovery after dental procedures. It also contributes to tooth staining, bad breath, and a higher risk of tooth loss over time.
Read the answerYes, nail biting puts repeated pressure on the front teeth, which can lead to chipping, uneven wear, and in some cases, subtle shifts in tooth alignment over the years. It can also worsen jaw tension for people who already grind or clench their teeth.
Read the answerTeeth aren't designed to handle the sudden, concentrated force involved in tearing or prying open packaging, which makes them prone to chipping or cracking, sometimes without any immediate pain. Damage from this habit often isn't noticed until the tooth is already compromised.
Read the answerSugar-free chewing gum can actually benefit oral health by stimulating saliva production, which helps neutralize acid and clear away food particles after meals. Sugared gum, on the other hand, feeds decay-causing bacteria and offers none of those protective benefits.
