How Does Teeth Whitening Work?

Everyone wants to have a beautiful, brilliant, white smile. But what if your teeth are more on the yellow side? Teeth whitening is a safe, effective, cost-efficient option for those looking to brighten their teeth. Keep reading to learn how teeth whitening works. 

Teeth Whitening Basics

Whitening is accomplished through bleaching. Whitening products contain a certain percentage of bleach, which attacks the yellow stains on your teeth and breaks them down to make them appear more white. Some offices will pair the bleaching gel with an LED light to complement the whitening process. 

It’s important to keep in mind that whitening will not work on all teeth. Teeth whitening works best on yellow teeth because yellowing is usually due to stains. On the other hand, brown and gray teeth which are discolored for reasons other than stains may not brighten much when bleached. 

If you are unsure whether teeth whitening will be effective for you, contact us at South Temple Dental . Our professionals will be glad to help you make the best decision.

The Science Behind Teeth Whitening

Most teeth whitening products contain peroxide-based whitening agents. According to McGill University, peroxide passes into the tooth and takes “the electrons that hold the atoms together, which in turn cause the staining molecules to fall apart .”

The amount of peroxide in whiteners varies. In general, WebMD reports that most home whitening systems contain 3–20% peroxide, but the treatments you can get at your local dentist’s office are likely to contain 15–43% peroxide. In other words, at-home bleaching kits are much less potent than the whitening treatments you can receive when overseen by a dentist.

At-Home Treatments 

As mentioned, at-home treatments are less powerful than whitening treatments you can receive in a dental office. They are usually cheaper than professional alternatives, but it can take longer to see results, and the results may not be as long-lasting. 

Here are some of the at-home whitening options available to you. 

Whitening Toothpaste

  • Pro: Inexpensive and easily available
  • Con: Usually do not contain bleaching agents
  • Con: Only lighten teeth a little bit (about one shade)
  • Con: Usually not left on the teeth long enough to have much of an effect

Whitening Strips and Gels

  • Pro: Contains peroxide
  • Pro: Inexpensive
  • Con: Can take up to two weeks to see results
  • Con: Results last only a few months

Bleaching Trays

  • Pro: Contains peroxide
  • Pro: Cheaper than professional alternatives
  • Con: Bleaching trays can still cost a few hundred dollars (especially if they are fitted to your mouth)
  • Con: You may have to wear the bleaching tray in your mouth for multiple hours every day
  • Con: Treatment process can take upwards of four weeks

In-Office Treatments

Whitening performed by a dentist in-office can have much more rapid results. Usually, patients can see dramatic results after the first treatment. 

At South Temple Dental, we offer whitening treatments for about $399 per session. Sessions last between 60 and 90 minutes.

Getting a tooth extracted can feel daunting, but understanding why extractions are sometimes necessary—and how to prepare for the procedure—helps alleviate anxiety. In many cases, removing a tooth can preserve and protect the overall integrity of your smile. By learning what to expect before, during, and after your appointment, you can confidently approach the process and set yourself up for a smooth recovery. Why Extractions Become Necessary Several factors can prompt a dental professional to recommend extracting a tooth. Severe decay that has compromised too much of the tooth’s structure may leave restoration efforts, such as fillings or crowns, insufficient for preserving oral health. In other situations, a tooth might be fractured or damaged beyond repair. Advanced periodontal (gum) disease affecting bone health can also lead to the need for an extraction, especially if it becomes challenging to support the stability of the affected tooth. Additionally, tooth extractions are sometimes part of comprehensive treatment plans to improve alignment or create adequate space in the mouth. If you have an impacted tooth—often a wisdom tooth that cannot fully emerge above the gum line—removal may be the best route to prevent infection and protect surrounding teeth. According to the Journal of the American Dental Association , extractions can also help manage overcrowding issues. While it’s normal to experience some worry about the process, early planning and open communication with your dental team often ease concerns and enable a confident mindset. Exploring the Procedure Modern dentistry places a significant emphasis on patient comfort, and tooth extraction procedures are typically performed under local anesthesia or another form of sedation. The first step usually involves thorough imaging—such as X-rays—to help your dentist evaluate the condition of the tooth and surrounding bone. This assessment ensures that if there are risks, such as curved or multiple roots, your dentist is well-prepared to navigate them and remove the tooth in the safest way possible. During a simple extraction, the dentist will numb the area around the tooth, and specialized tools gently loosen the tooth from its socket. If the tooth in question has not fully erupted or is severely fractured, a surgical extraction may be required. In this instance, small incisions in the gum tissue provide access to safely remove the tooth. Regardless of the method, your dental team strives to keep you comfortable throughout. You might feel pressure during the procedure, but pain sensations should be minimal. If you experience discomfort, it’s important to communicate immediately with your dental professional so they can adjust your level of anesthesia or sedation. Helpful Tips for a Stress-Free Experience Because dental visits can stir up apprehension in some patients, taking a few simple steps beforehand makes a difference in how you feel. Plan to discuss any existing medical conditions, allergies, or medications with your dentist in advance. This helps your dental team tailor the treatment plan to your specific needs and ensure optimal safety. Avoid eating a large meal directly before an extraction if you’ll be sedated, but do follow any instructions your dentist provides regarding water intake or light snacking. Preparation extends beyond the logistical details. For instance, calming exercises—like diaphragmatic breathing or gentle stretching—can help relax your mind while you wait. If you have concerns about the procedure itself, talking openly with your dentist or hygienist often relieves worries. They can walk you through exactly what to expect, address any fears, and discuss customization options like sedation. Remember that choosing a trusted dental practice that prioritizes clear communication is a vital step toward a worry-free experience. Post-Extraction Care for a Successful Recovery The recovery phase plays a critical role in ensuring that your mouth heals swiftly and thoroughly. Immediately after an extraction, it is common to apply gauze to the site, helping to control bleeding and create a blood clot. Be mindful not to disturb the clot, as it protects the underlying bone and nerve endings. Avoid rinsing your mouth vigorously, drinking through a straw, or consuming overly hot foods for at least the first 24 hours. Doing so might dislodge the clot and prolong healing. As your mouth recovers, stick to soft foods that require minimal chewing—soups, yogurt, applesauce, and mashed vegetables are typically easy to manage. Make sure to drink plenty of fluids but limit alcoholic or caffeinated beverages, as they can slow the healing process. Good oral hygiene is still essential, but be gentle around the extraction site. Carefully brushing off plaque in other areas of the mouth and rinsing lightly with a mild saline solution—recommended by many dentists and backed by Mayo Clinic —can keep the healing site clean without creating irritation. If you notice persistent swelling, prolonged bleeding, or discomfort that worsens over time, contact your dentist promptly. Planning Your Follow-Up Visit After an extraction, follow-up visits help gauge the progress of your recovery. Your dentist may recommend an appointment around a week or two later to make sure the socket is healing well and to check for any complications. This visit is also an excellent time to discuss a long-term plan for replacing the extracted tooth if needed. Options like dental implants, bridges, or partial dentures are popular methods to address gaps, enhance aesthetics, and maintain proper chewing function. By consulting with your dental professional, you’ll gain personalized insights into whether a temporary restorative solution or a permanent replacement is best suited for you. Investing in a timely replacement not only preserves your smile’s appearance but also supports the integrity of your remaining teeth. Missing teeth can shift over time, and your jawbone health may be affected if they are not replaced. Addressing these concerns early ensures a strong foundation for your continued oral wellness. Where to Learn More and Take the Next Step Recovering from a tooth extraction can be more straightforward than you might imagine when you are equipped with the right information and a caring dental team. Having a clear plan, understanding the procedure, and knowing how to care for yourself afterward make all the difference in feeling confident about your oral health journey.

Dental sealants offer a proactive way to protect young teeth from cavities, helping children maintain happier, healthier smiles. By forming a strong shield against harmful bacteria, sealants can significantly reduce the risk of tooth decay over the long haul. Below, we delve into how this preventive measure works, the recommended age for receiving them, and the common myths that sometimes surround dental sealants. Understanding the Power of Dental Sealants The concept behind dental sealants is simple yet powerful: a thin, protective coating is placed on the chewing surfaces of back teeth (molars and premolars) to keep food debris and bacteria from settling into the grooves. According to the Centers for Disease Control and Prevention (CDC) , dental sealants have the potential to prevent up to 80% of cavities in the back teeth—the most common area children develop cavities. While brushing twice a day and flossing daily remain crucial, sealants serve as a valuable extra line of defense. Even the most thorough at-home cleaning can miss tiny crevices that house bacteria. Elastic sealants fill those small nooks, preventing decay at its earliest stages. How Sealants Protect Growing Smiles When a child gets a sealant, the tooth surface is first cleaned and dried. Afterward, a solution is gently applied to the tooth to help the sealant bond better. The final step is painting the sealant onto the enamel, where it hardens within seconds under a special curing light. Because the sealant is almost invisible, children can enjoy capped protection without any impact on speech, chewing, or appearance. Once applied, sealants form a reliable barrier that can last for several years, though regular dental checkups will confirm if sealants need reapplication. The American Dental Association (ADA) endorses the use of sealants as an effective form of cavity prevention, as noted in their sealant guidelines . By supplementing routine brushing and flossing, this added shield can provide an extra layer of security for developing smiles. Ideal Age for Dental Sealants Children begin to get their permanent molars around age six, with additional molars appearing in their early teens. During these formative years, introducing dental sealants is often recommended. By coating the back teeth soon after they come in, the risk of cavities can be greatly minimized. While the ideal window for applying sealants is generally around the age children receive their permanent molars, it is never too late to consider this treatment if your child is prone to cavities or has deeply grooved teeth. Talking with a trusted pediatric or general dentist about your child’s dental health history can help determine the right time to apply sealants. Common Myths, Clarified Even with a solid record of success, questions sometimes arise about dental sealants. Let’s address a few: “Sealants contain harmful substances.” Modern sealants are designed to be safe and effective. Many are BPA-free, and any concerns about chemical exposure should be discussed directly with your dentist, who can verify specific product information. “Fluoride does the same job as sealants.” Although fluoride (in toothpaste, mouthwash, and tap water) strengthens enamel and helps resist decay, sealants specifically protect the areas that are most vulnerable to bacteria and plaque. Both fluoride and sealants work together within a comprehensive cavity-prevention strategy. “Sealants make it harder to clean teeth.” In reality, sealants can make brushing more effective by smoothing over the deep grooves that often trap food. Dental hygiene routines continue as normal, and your child’s dentist will still check on the integrity of the sealants at regular visits. Moving Forward Toward Healthier Smiles One of the most rewarding aspects of dental sealants is the boost it gives to both parents and kids. Parents breathe easier knowing they’ve proactively reinforced their child’s teeth, and children feel more enthusiastic about their dental visits when they know they have an extra layer of protection against cavities. In addition to these benefits, maintaining a consistent oral hygiene routine at home remains essential. By combining the protective power of sealants with proper brushing, flossing, and regular dental checkups, you’ll encourage a lifetime of strong and healthy teeth. As your child grows, their dentist can keep an eye on how well the sealants are holding up, ensuring a truly long-lasting defense.
