A Comprehensive Solution for Tooth Replacement
Zirconia crowns can withstand high chewing forces, are resistant to breakage, and provide a natural appearance in the mouth. They are frequently used on back teeth, front teeth, full mouth restorations, and implant-supported crowns. For this reason, individuals want to use their crowns for many years with proper care, keeping them looking as good as new.
Care must be taken when maintaining zirconia crowns. The surface of the crowns can be damaged, especially by incorrect oral care products. In addition, the gum and bone tissue surrounding zirconia crowns must also be protected for long-term use. Therefore, the choice of toothpaste is an important detail.
Zirconia crowns are resistant to discolouration and scratches thanks to their strong structure. However, depending on usage, the shiny surface may become damaged, causing the crown to lose its shine. In addition, people who frequently consume tea, coffee, wine, and acidic drinks may experience discolouration and acid-related wear on their crowns. Although people may think that using whitening toothpaste is necessary to protect their crowns from discolouration, this is not correct.
Most toothpastes are produced for natural tooth enamel and contain abrasive particles to remove stains. Over time, these toothpastes roughen the zirconia surface. Rough surfaces trap plaque more easily. Plaque build-up increases the risk of gum inflammation, bleeding, and peri-implant issues in implant cases. These conditions often go unnoticed until they cause pain.
The purpose of the ideal toothpaste for zirconia crowns is clear: to provide effective cleaning without damaging the surface.
RDA (Relative Dentin Abrasivity) is a measure of how abrasive a toothpaste is. Toothpastes with low abrasiveness have an RDA value below 70. Medium abrasiveness ranges from 70 to 100. Those with RDA values above 100 are highly abrasive.
Toothpastes with low abrasiveness preserve the surface shine of crowns. Most whitening toothpastes remove surface stains by abrasion, making teeth appear whiter. The colour of zirconia crowns is fixed and does not whiten. Using whitening toothpaste does not whiten the crown but damages the surface.
Abrasives such as diamond powder, calcium carbonate, and charcoal, found in high concentrations in abrasive toothpastes, can damage zirconia crowns. Whitening toothpastes should not be part of your daily routine. Using them once a week is more appropriate. Strong whitening agents used for whitening can irritate the gums and damage tooth enamel and crown edges.
The best toothpaste for zirconia crowns is one that is gentle yet effective. Hydrated silica, used in controlled amounts, is generally safe. Sensitivity-reducing ingredients used in patients with tooth sensitivity do not damage the zirconia surface.
Low-abrasive toothpastes are ideal for patients with multiple zirconia restorations. These products provide plaque control through chemical means. Venneir brand toothpaste is specially formulated for restorations such as crowns, implants, and veneers. It features a non-abrasive formula, gentle whitening power, sensitivity safety, and no nasties.
Yes, fluoride is safe and recommended when used in sufficient quantities. Zirconia does not require fluoride, but it is necessary for the surrounding natural teeth and root surfaces. Fluoride reduces the risk of tooth decay. Fluoride does not damage zirconia crowns on implants or the implant itself.
Zirconia crowns should be brushed twice a day. A pea-sized amount of toothpaste should be applied to a soft-bristled toothbrush. Then, gently clean all surfaces of the teeth using light pressure and sweeping motions. After a 2-minute cleaning session, rinse your mouth. Vigorous back-and-forth brushing can cause surface wear and gum recession. More effective results can be achieved with the sensitive brushing option on electric toothbrushes.
Zirconia crowns cannot be whitened with toothpaste or teeth whitening methods. On the contrary, these damage the crown surfaces. They make them susceptible to discolouration and wear. In addition to gentle and regular cleaning, developing the habit of rinsing your mouth after eating and drinking is beneficial for the long-term use of the crowns. Polishing by a dentist once a year restores the crowns to almost their original condition.
Any brand of toothpaste, such as Sensodyne or Colgate, can be used for zirconia crowns. Only toothpastes with whitening properties should be avoided. For patients who want a more sensitive cleaning, gentle toothpastes that clean gently can be preferred. For example, Sensodyne's sensitivity, gum & enamel, extra fresh, and deep clean products may be preferred.
