8 September, 2026SKĐS – Cleaning teeth is not simply about removing visible tartar; it also requires controlling stains and discoloration in hard-to-reach areas.
1. What exactly is tartar and how does it form?
To make it easier to understand, this process is similar to the way limescale builds up inside a kettle at home. The formation of tartar actually occurs much faster than we might think, beginning just minutes after eating. At this point, a thin film from saliva covers the surface of the teeth, acting like an invisible piece of double-sided tape, making it easier for food debris and bacteria to adhere to the teeth.
If cleaning is neglected, within just a few hours, bacteria will “feed” on these food particles and multiply, forming a soft, opaque white layer known as dental plaque. At this stage, the situation is still under control because you can completely remove the plaque yourself by brushing your teeth thoroughly or using dental floss.
However, if you “forget” to clean away the plaque, a turning point occurs after 2 to 3 days. Minerals in saliva begin to penetrate the soft layer and initiate a process of “petrification.” At this point, the plaque turns into hard tartar (dental calculus) that firmly adheres to the teeth like concrete. Once it has reached this stage, a toothbrush or ordinary dental floss can no longer remove it, and you need assistance from a dentist or dental professional to have the tartar removed.
2. Why is it necessary to have tartar removed regularly?
Many of us still think: “I brush my teeth carefully 2–3 times a day, and my teeth still look white, so why should I spend money having my tartar removed?” But the truth is that no matter how skillfully you brush your teeth, there are always “dead spots” in the mouth that a toothbrush cannot reach. These areas are highly susceptible to plaque and tartar buildup.
Tartar is not simply a few harmless deposits of mineralized material. It acts as a reservoir for millions of bacteria and can lead to a number of consequences, including:
- Bad breath and bleeding gums: Bacteria in tartar continuously release toxins that cause the gums to become swollen and red, making them prone to bleeding when brushing and causing unpleasant breath.
- Tooth loss: The deeper tartar accumulates, the more it can contribute to gum recession. Over time, the bone supporting the tooth roots may be lost, causing the teeth to become loose and eventually fall out completely.
- Tooth decay.
3. What is “bio-salt air” dental scaling? How is it better than conventional equipment?
If you have ever been afraid of dental scaling because of the “buzzing” sound and sensitivity caused by conventional metal scaling instruments, bio-salt air polishing technology may be an optimal option for you. Dental scaling systems using bio-salt air have several advantages:

- No sharp metal instruments: The system uses an extremely fine stream of warm water combined with compressed air and fine bio-salt powder, as fine as powder, to remove plaque and yellowish stains caused by tea, coffee, and tobacco.
- Extremely gentle with minimal sensitivity: You may simply feel as if your teeth are being gently massaged, with a slightly sweet taste, without pain or sensitivity to the tooth enamel.
- Cleans hard-to-reach areas: The fine water spray can easily reach very narrow interdental spaces that conventional instrument tips may not be able to access.
- Effectively removes plaque and stains: It can remove discoloration caused by coffee, tea, tobacco, or food that may be difficult to address with conventional dental scaling alone.
- Minimally invasive and helps preserve tooth enamel: The use of ultra-fine powder particles combined with air and water allows for gentle cleaning while helping limit damage to the tooth surface and gum tissue.
4. Dental scaling with a bio-salt air system is particularly important for people with dental implants
A dental implant (an artificial tooth root placed into the jawbone) has an extremely sensitive component: a polished ceramic or metal connection located close to the gums. This component is made extremely smooth to prevent bacteria from adhering to its surface.
- The risks of conventional scaling: If sharp metal instruments are used around a dental implant, they may scratch this connection. These scratches can then become “hiding places” for bacteria to accumulate, potentially increasing the risk of inflammation, bone loss, and ultimately implant failure.
- Why use bio-salt air polishing? Ultra-fine salt powder particles can gently remove plaque around dental implants without causing scratches. This is an important approach to helping protect your implants and maintain their longevity.
Dental scaling with a bio-salt air system is a modern tooth-cleaning method that uses a combination of air, water, and ultra-fine powder particles to effectively remove biological plaque, soft tartar, and stains caused by tea, coffee, or tobacco. Compared with conventional methods, this technique provides gentler cleaning, reduces the sensation of tooth sensitivity, and helps minimize potential damage to tooth enamel and gum tissue. At the same time, the bio-salt air system can clean hard-to-reach areas such as interdental spaces, pits and fissures, around orthodontic brackets, dental restorations, and implants, helping remove bacteria that contribute to gingivitis, periodontitis, and bad breath. As a result, teeth are not only cleaner and brighter after treatment but can also be maintained in good oral health over the long term, helping effectively prevent oral diseases.
