    牙膏種類逐個數!牙膏成分功效一一拆解 | 附優惠資訊

    Step into the toothpaste aisle of a supermarket, you’d find yourself amidst an overwhelming array of choices. The dazzling promises of teeth whitening and cavity protection beckon from every shelf. But have you ever wondered what is in them and what ingredients are the real MVP?

    Today, Spot On is going to unravel the mysteries of toothpaste ingredients with you, explore how they work and uncover any potential side effects. By the end, you'll be armed with the knowledge to choose the toothpaste that best serves your unique oral needs.

    Commonly Found Ingredients in Toothpastes

    Fluoride: Fight Cavities

    When it comes to toothpaste, one ingredient stands out as an essential against tooth decay: fluoride. Its importance cannot be overstated, making it a staple in oral care products. In fact, the Hong Kong government even started adding fluoride to the drinking water in 1961 to safeguard the oral health of its citizens.

    Fluoride toothpaste
    Most of the toothpaste in the market contains fluoride

    Fluoride works wonders by reducing oral bacteria, curbing the buildup of dental plaque, thus thwarting the release of harmful acids by bacteria - all of which contribute to tooth decay prevention. But same as everything else, fluoride should be used in moderation.

    True or False: Fluoride leads to fluorosis?

    It’s true that excessive intake of fluoride in children under 8 years old can result in a condition called fluorosis. Symptoms include unsightly white or yellow streaks on the tooth surface that could potentially impact appearance. In worse cases, fluorosis would weaken teeth and make them prone to breakage.

    Fortunately, fluorosis is a rarity in Hong Kong. It only occurs when fluoride is consumed in exceedingly high concentrations. It is almost impossible to get fluorosis by correctly using dental products that you can get in the market. In other words, it is totally okay to choose a toothpaste that contains fluoride.

    Synthetic Detergents: The foam maker

    Ever wondered why toothpaste foams up when you brush? Synthetic detergents, also known as foaming agents, are the answer. Some toothpaste with low or no foaming capabilities may contain a smaller amount or none of these synthetic detergents.

    However, it's essential to strike a balance. Excessive synthetic detergent can irritate the oral mucosa, leading to discomfort. Rest assured, though, that formulas of major toothpaste brands meet safety standards, ensuring they pose no harm to the human body. If you still have concerns, tooth powder without foaming capabilities can serve as an alternative.

    What if there’s no foam in your toothpaste?

    The bubbly texture of toothpaste makes it feel more delicate, and some people may find using unfoamy toothpaste uncomfortable. The foam also helps to effortlessly envelop all teeth, ensuring that the cleaning bubbles make contact with every part of your teeth, even if you're not brushing with utmost precision.

    Abrasives

    Meet the unsung hero of toothpaste: abrasives. Different toothpaste brands employ various abrasive components, but they all allow you to remove surface stains and dental plaque through gentle scrubbing.

    True or False: Abrasives could damage the tooth surface?

    Toothpaste with excessive or rough abrasives, coupled with long-term use or excessive brushing force, can damage the protective enamel. This can leave the tooth surface rough and vulnerable to stain deposition, leading to tooth sensitivity and discomfort while consuming sweet, sour, or cold treats.

    To protect your enamel, it's recommended that you brush your teeth with care, tilting the toothbrush at the appropriate angle and brush gently, so that the risk of enamel damage from the abrasive content in toothpaste is minimised.

    While fluoride, synthetic detergents, and abrasives play vital roles in almost every tube of toothpaste, there are other ingredients that possess special effects and provide unique benefits.

    Whitening Toothpaste

    Whitening toothpaste boasts coarser or more abundant abrasive particles designed to effectively remove dental stains, restoring the teeth to their original luster.

    True or False: Whitening toothpaste is not suitable for long-term use

    True. Dentists advise against long-term use of whitening toothpaste to prevent enamel damage caused by the abrasive nature of the product. Once a tube of whitening toothpaste is finished or has achieved the desired effect, it is recommended that you switch to a non-whitening toothpaste. Whitening toothpaste can be reintroduced if dental stains accumulate in the future. Please also note that whitening toothpaste is not recommended for children with thinner teeth.

    True or False: The effect of whitening toothpaste is limited

    It’s true. Individuals with minimal dental stains may not experience significant results from using whitening toothpaste alone. This type of toothpaste primarily targets surface stains and cannot whiten the natural color of the tooth.

    If your teeth are naturally yellow, which is not an oral health concern, but still desire to improve their appearance, you may consider visiting a dental clinic for treatments such as laser whitening or teeth bleaching.

    Sensitive Relief Toothpaste

    Sensitive relief toothpaste addresses the issue of sensitive teeth, which occurs when the enamel surface is damaged, exposing the more vulnerable dentin. When stimuli, such as sour and sweet food or cold sensations, reach the dentin's surface through the dentin tubules, sensory signals are transmitted to the nerve-filled dental pulp, resulting in tooth sensitivity.

    Sensitive toothpaste tackles this problem through two primary methods - the first one aims to block the dentin tubules, so that food stimuli do not reach the dental pulp, thus reducing tooth sensitivity. The second method achieves its results by reducing the sensitivity of the dental pulp nerves to minimize discomfort.

    True or False: Sensitive Relief toothpaste is not suitable for long-term use

    False. The effectiveness of sensitivity relief toothpastes varies, depending on the severity of tooth sensitivity. Some people feel the effect in a few days, while others may have to use the toothpaste twice a day for up to four weeks before they feel better. Continue using after you feel the effect for sustained relief.

    For immediate relief, apply sensitivity relief toothpaste directly to the tooth surface with a finger and leave it on for 3 - 5 minutes. If there is no improvement or if symptoms worsen after using your sensitivity relief toothpaste for 2 months, make sure you consult a dentist, as tooth sensitivity may also indicate other underlying oral health issues.

    Anti-cavity Toothpaste

    Anti-cavity toothpaste is the best guard to fight tooth decay. Except fluoride, which is a staple ingredient in anti-cavity toothpastes, some anti-cavity toothpaste also includes calcium to help strengthen and fortify tooth enamel.

    Additionally, some anti-cavity toothpaste utilizes acid-neutralizing technology to reduce the chances of acid erosion on teeth. Tooth decay is mostly caused by lactic acid broken down from sugars. By neutralizing the acid, toothpaste can help prevent tooth decay.

    If you have been maintaining good oral health (well done!) and you don't need toothpastes with specific effects to treat your dental problems, we recommend you to use anti-cavity toothpaste in your dental care routine.

    True or False: I have cavity, it’s too late to use an anti-cavity toothpaste

    It’s not true. Although anti-cavity toothpastes are known for their preventive effect, it is particularly important to use anti-cavity toothpaste if you have decayed teeth, especially at the early stages. These toothpastes can enhance the remineralization process which repairs the process of tooth enamel that can reverse tooth decay in early stages, potentially avoiding the need for dental fillings. However, if the cavities have been present for a while or show signs of worsening, please seek treatment at a dental clinic.

    Fresh Breath Toothpaste

    Fresh breath toothpaste is specifically formulated to combat bad breath and provide long-lasting freshness. While regular toothpaste with antimicrobial effects can alleviate breath problems caused by bacteria, fresh breath toothpaste emphasizes the use of peppermint essence and other flavorings to enhance the breath-freshening effect.

    Remember, if your bad breath persists despite using fresh breath toothpaste, it may be the consequence of other oral problems such as cavities, mouth ulcers, or gum inflammation. Regular dental check-ups are essential to identify and address any underlying issues.

    Tips for choosing fresh breath toothpaste:

    More and more flavors have been rolled out in the toothpaste market, some of the most effective breath-freshening toothpastes are in herbal flavors, like green tea or jasmine. You can choose a toothpaste flavor based solely on your personal preference.

    Some fresh breath toothpaste may indicate the duration of fresh breath maintenance on the packaging. Toothpaste that can maintain fresh breath for 24 hours typically has stronger efficacy and is recommended for individuals troubled by persistent bad breath.

    Gum Care Toothpaste

    If you're dealing with gum issues, gum care toothpaste could be the right choice. Gum problems are often caused by bacteria and poor oral hygiene. When bacteria build up along the gumline, it can make your gums swell and even bleed. Gum care toothpaste usually contains sodium bicarbonate, which has smaller particles that can reach those tricky areas, remove plaque, and ease gum irritation from bacteria and plaque. This can bring relief and help prevent gum problems.

    True or False: Bleeding gum is not a big deal - No need to use gum care toothpaste at this stage

    A big false! It's crucial not to ignore gum problems because untreated periodontal disease can lead to gum recession and, eventually, tooth loss. If using gum care toothpaste doesn't improve your gum condition or if your condition worsens, it's important to see a dentist to receive the right treatment.

    Kids Toothpaste

    Kids toothpaste is formulated specifically for children’s milk teeth and takes into account their unique dental needs. As children are more prone to risks associated with fluoride intake, children's toothpaste generally contains a lower amount of fluoride. Some kids toothpaste partially replaces fluoride with xylitol to achieve the preventive effect against tooth decay while minimizing the risk of fluorosis.

    Xylitol is a natural sweetener that adds sweetness to children's toothpaste without producing acidity. While xylitol makes the taste of toothpaste more appealing to children, it also helps prevent bacteria from adhering to the tooth surface and reduce the accumulation of dental plaque, which contributes to tooth decay.

    When should kids switch to adults’ toothpaste?

    It's important to note that children's toothpaste is specifically designed for cleaning primary teeth. Dentists recommend switching to adult toothpaste once permanent teeth erupt to ensure proper cleaning and protection.
