With the increasing demand for oral beauty and teeth whitening among modern people, a variety of teeth whitening technologies have appeared on the market. Among them, biological sea salt sandblasting and cold light whitening , as two of the more common methods, have received widespread attention. This article will conduct a systematic analysis of the principles, effects, safety and applicable populations of these two technologies, in order to provide scientific reference for clinical beauty and consumers.
1. Technical principles and characteristics of biological sea salt sandblasting
Biological sea salt sandblasting is a mechanical cleaning technology that uses high-pressure spray of a biological sea salt mixture containing fine particles to physically clean the tooth surface. Its main function is to remove pigment deposits and dental plaque on the tooth surface and restore the natural whiteness of the teeth. Biological sea salt ingredients are usually derived from natural sea salt and contain a variety of trace minerals, which help to smooth the tooth surface and improve the oral environment.
The advantages of biological sea salt blasting include:
Mechanically removes stains on the tooth surface with rapid results , and is especially suitable for removing exogenous pigments such as smoke stains and tea stains.
It causes less damage to tooth tissue , the operation process is gentle, and the patient is more comfortable.
Assists in oral hygiene maintenance . The tooth surface is smooth after sandblasting, which is more conducive to daily cleaning and reduces plaque accumulation.
However, the limitations of biological sea salt sandblasting are also quite obvious. The main thing is that its whitening effect is a surface improvement and cannot penetrate into the pigment deposition inside the enamel. Therefore, it has limited effect on endogenous staining and yellow teeth.
2. Technical principles and characteristics of cold light whitening
Cold light whitening technology belongs to the category of photocatalytic whitening. Its principle is to combine professional whitening agents (usually containing peroxide ingredients) with cold light irradiation of a specific wavelength to accelerate the release of active oxygen and decompose the pigment molecules inside and on the surface of the teeth , thereby achieving a more thorough whitening effect. The light emitted by the cold light lamp is a blue light without thermal energy, which can effectively activate the ingredients in the whitening agent while avoiding pulp discomfort caused by overheating.
The main advantages of cold light whitening include:
It can penetrate tooth enamel and break down deep pigments , providing significant and long-lasting whitening effects.
The treatment process is relatively fast and is generally completed within 1 to 2 hours , which meets the needs of modern fast-paced life.
The operation process is professional, and the doctor can adjust the treatment plan according to the patient's dental condition , with better individualized results.
The disadvantage of cold light whitening is that the use of whitening agents containing peroxide may cause a certain degree of tooth sensitivity or gum irritation, and is not suitable for some patients with dental diseases. In addition, the treatment cost is relatively high, and it is highly dependent on technology and equipment.
3. Safety Comparison
Since biological sea salt sandblasting has mechanical cleaning properties, it has little impact on enamel and dentin and fewer side effects. It is suitable for daily maintenance and people with mild pigmentation. It is relatively safe, easy to operate, and has good patient compliance.
Although cold light whitening has a strong whitening effect, the use of peroxide brings a significant risk of tooth sensitivity. Studies have shown that some patients may experience short-term toothache or gum discomfort after treatment, but most of them will be relieved within a few days. Clinically, doctors will adjust the concentration and irradiation time according to the patient's oral condition to reduce the incidence of adverse reactions.
IV. Applicable population and contraindications
Biological sea salt sandblasting is suitable for individuals with superficial pigmentation and no obvious structural damage to their teeth, especially smokers and people who drink a lot of tea and coffee. It is suitable for people who need regular cleaning and maintenance of the whiteness of their teeth.
Cold light whitening is more suitable for individuals with internal pigmentation, yellow teeth and higher requirements for whitening. It requires patients with healthy teeth and no oral diseases such as pulp inflammation and caries to participate in the treatment.
In terms of contraindications, pregnant women, breastfeeding women, children, and people with obvious tooth sensitivity or periodontal disease should avoid using cold light whitening and give priority to the milder biological sea salt sandblasting.
5. Effect sustainability and maintenance recommendations
The effects of biological sea salt sandblasting are mostly short-term, and usually require good oral hygiene habits and regular follow-up visits to maintain good tooth cleanliness. The smooth tooth surface after sandblasting helps reduce pigment deposition and delay tooth discoloration.
The effect of cold light whitening generally lasts from 6 months to 1 year, which is affected by lifestyle habits, diet structure and oral care. It is recommended to avoid smoking, reduce coffee and tea drinking after treatment, and use appropriate whitening toothpaste for auxiliary maintenance.
VI. Comprehensive Evaluation
Biological sea salt sandblasting and cold light whitening each have their own advantages and limitations. People with different needs can choose the corresponding technology. Biological sea salt sandblasting focuses more on daily maintenance and superficial stain removal. It is easy to operate and highly safe. Cold light whitening is suitable for people who pursue more significant whitening effects, but they need to weigh sensitive risks and cost issues.
In actual application, professional doctors often recommend the combination of two methods: first remove surface stains through biological sea salt sandblasting, and then enhance the internal color through cold light whitening to achieve a more ideal whitening effect.
The field of cosmetic dentistry is still developing, and related technologies will be more accurate, safe and efficient in the future. Clinicians should develop personalized treatment plans based on the patient's oral condition, pigment type and whitening needs.
Beauty Encyclopedia Tips: When choosing a teeth whitening method, you should consider your own dental health and lifestyle habits, consult a professional dentist, avoid blindly using improper techniques, maintain good oral hygiene and regular check-ups, which are important guarantees for maintaining dental health and beauty.
