We’ve all been there. You take a refreshing sip of ice-cold water or a bite of your favorite gelato, and suddenly, zing!, a sharp, shooting pain flashes through your teeth. It’s a literal headache in your mouth, and it can turn a pleasant meal into a painful ordeal in seconds.
If you’re living in Surrey or Clayton and find yourself cringing every time the temperature of your food changes, you aren't alone. Tooth sensitivity (or what we call "dentin hypersensitivity" in the clinical world) is incredibly common. But here’s the thing: while sensitivity is common, many people are accidentally making it worse through their daily habits.
At BigSmiles Dental Care, Dr. Larry Lu and our team see patients every day who are doing their best to take care of their teeth but are inadvertently causing more harm than good. To help you get back to enjoying your morning coffee and evening treats without the "ouch," we’ve rounded up the seven most common mistakes people make with sensitive teeth, and, more importantly, how to fix them.
One of the biggest misconceptions in oral hygiene is that the harder you brush, the cleaner your teeth will be. In reality, your teeth aren't like a dirty garage floor that needs a heavy scrub.
When you use too much pressure, you aren't just removing plaque; you’re actually wearing down your enamel. Enamel is the hard, protective outer layer of your tooth. Once it thins out, the underlying layer called dentin is exposed. Dentin contains tiny microscopic tubes that lead directly to the nerve of your tooth. When hot or cold hits those tubes? You guessed it: pain.
The Fix: Think of brushing as a gentle massage for your teeth and gums. Use light, circular motions. If the bristles on your toothbrush are splayed out or flattened after a few weeks, you’re definitely pressing too hard.
When you’re at the store in Clayton looking for a new toothbrush, those "firm" or "medium" bristles might look like they mean business. However, for most people, especially those with sensitivity, a firm toothbrush is like using sandpaper on a finished piece of wood.
Hard bristles are a leading cause of gum recession. When your gums recede, they pull away from the tooth, exposing the root. Unlike the crown of your tooth, the root doesn't have a thick enamel coating, making it extremely sensitive to almost everything.
The Fix: Always opt for "soft" or "extra-soft" bristles. They are more than capable of removing plaque without damaging your delicate gum tissue or enamel. According to Delta Dental, soft-bristled brushes are the gold standard for maintaining a healthy, pain-free smile.
We love our morning lattes and the occasional bubbly drink, but your teeth might not feel the same way. Highly acidic foods and drinks act like a slow-motion solvent on your enamel. Over time, frequent exposure to acids found in soda, wine, citrus fruits, and even some sports drinks can cause "acid erosion."
The mistake many people make isn't just consuming these things, it's how they consume them. Sipping an acidic drink over several hours keeps your mouth in a constant state of "acid attack," giving your saliva no time to neutralize the pH levels and remineralize your enamel.
The Fix: You don’t have to give up your favorites entirely. Try drinking acidic beverages through a straw to bypass your teeth, and follow them up with a glass of plain water to rinse away the residue. Most importantly, wait at least 30 minutes after consuming something acidic before brushing; your enamel is temporarily softened by the acid, and brushing too soon can actually scrub it away!
Do you ever wake up with a dull headache or a sore jaw? You might be a "bruxer", someone who grinds or clenches their teeth during sleep. This is one of the fastest ways to destroy enamel and cause widespread tooth sensitivity.
Grinding puts immense pressure on your teeth, leading to micro-fractures and wearing down the biting surfaces. Over time, this wear-and-tear exposes the dentin, making your whole mouth feel sensitive to temperature changes.
The Fix: If you suspect you're grinding, mention it during your next routine dental check-up in Surrey. Dr. Lu can check for signs of wear and provide a custom-fitted night guard. This simple device acts as a cushion, protecting your teeth from the force of grinding while you sleep.
Everyone wants a Hollywood smile, but over-the-counter whitening kits can be very harsh. Many DIY whitening strips and gels use high concentrations of peroxide that can penetrate the enamel and irritate the nerves inside your teeth.
The mistake is using these products too frequently or leaving them on longer than recommended in hopes of faster results. This often leads to "zingers", sharp stabs of pain that can last for days after whitening.
The Fix: If you have sensitive teeth but still want a brighter smile, talk to us about professional whitening options. At BigSmiles Dental Care, we can tailor a treatment that uses desensitizing agents to keep you comfortable. Always look for products with a seal of approval and never exceed the recommended usage.
When your teeth hurt, it’s easy to just switch to a desensitizing toothpaste and call it a day. While these toothpastes (like those containing potassium nitrate) are great at blocking the pain signals, they don’t actually "fix" the underlying issue.
Sensitivity can be a "canary in the coal mine" for other problems like a hidden cavity, a cracked tooth, or early-stage gum disease. By only treating the pain, you might be allowing a small problem to turn into a major (and expensive) one.
The Fix: Think of sensitivity as your body’s way of asking for help. If the pain persists for more than a few days, it’s time to see a professional. As an experienced dentist in Clayton, Dr. Larry Lu can perform a thorough exam to determine if your sensitivity is just thin enamel or something that requires a more specific treatment, like a root canal or a protective filling.
The biggest mistake of all? Waiting until you are in agony to book an appointment. Many patients skip their dental cleanings because "nothing hurts." However, preventative care is the best way to catch the enamel wear and gum recession that cause sensitivity before they become painful.
During a professional cleaning, we remove hardened tartar (calculus) that you can’t get off at home. Tartar buildup is a major cause of gum recession, which, as we mentioned earlier, is a direct ticket to sensitive-tooth-city.
The Fix: Stick to your six-month schedule. A quick routine dental check-up in Surrey allows us to apply fluoride varnishes or sealants that strengthen your enamel and provide an extra layer of protection against sensitivity.
