6 Signs to Recognise Genuine and Low-Quality Dental Crowns
Dental crowns are a popular solution for restoring function and aesthetics to teeth, but distinguishing between genuine and low-quality crowns is not always easy. Understanding this, the East Rose Dental Clinic has compiled six signs to recognise low-quality dental crowns and tips to help you shine with high-quality crowns in the article below.
What are genuine dental crowns?
Reputable brands manufacture genuine dental crowns, guaranteeing their quality with clear origins and accompanying certification and warranty documents. They are crafted from premium materials such as zirconia and E-max porcelain, offering high durability, natural colour, and excellent strength. Genuine crowns can restore chewing function and enhance the aesthetic appearance of your smile. Additionally, they are highly compatible with gum tissue and do not cause irritation. Therefore, using genuine dental crowns ensures safety and long-term effectiveness for your oral health.
6 Signs to Identify Low-Quality Dental Crowns
Using low-quality dental crowns can not only affect aesthetics but also cause serious issues for your oral health. Therefore, to avoid wasting money and facing health problems, remember the following signs.
No clear origin and a lack of an official warranty card

Typically, genuine dental crowns come with an official warranty card from the supplier. Low-quality crowns often lack a clear origin, have no official warranty information, or cannot be traced back to official websites. Genuine crowns will provide clear information about the manufacturer and come with an official warranty card, ensuring product quality and allowing you to verify its origin.
Additionally, if there is a significant price difference for the same type of porcelain material, you should reconsider. This is because counterfeit dental crowns are often surprisingly cheap due to their unclear origin and lack of proper certification and documentation.
Uneven colour and yellowing over time.
Low-quality dental crowns often have an uneven colour that is easily noticeable to the naked eye, especially under bright light where a blackish hue may appear. If the crown is unnaturally bright white or has a dull, greyish colour, it could indicate the use of poor-quality materials. Genuine crowns typically have a natural color—not too white or too dark—with transparency similar to real teeth.
Additionally, low-quality crowns often discolour quickly after some wear. This happens because the materials lack resistance to food stains, tobacco, and external factors. Genuine dental crowns maintain their colour over time, and they do not yellow or discolour with prolonged use.
Prone to Abrasion, Chipping, or Breaking

Non-metallic dental crowns typically undergo firing at temperatures exceeding 1350°C, ensuring their extreme hardness and durability. Therefore, if a dental crown breaks, chips, or wears down quickly in a short period, it is definitely a sign of low-quality crowns. This not only affects aesthetics but also reduces the chewing function for the user.
Unnatural Sensation When Using
Low-quality dental crowns often have a rough surface, causing discomfort for the user, especially when in contact with the gums. Genuine dental crowns are designed with a smooth surface and proper thickness, minimising the feeling of bulkiness, fitting well with the gum tissue, and offering comfort during chewing.
A noticeable sign is when the crown comes into contact with hot or cold food, the user may experience pain or sensitivity. Low-quality crowns lack good thermal insulation, leading to discomfort during use.
Poor Biocompatibility
Low-quality dental crowns may not be very compatible with gum tissue, causing irritation or infections. This can lead to bleeding gums, pain, or a feeling that the gums and crown are not properly connected when laughing or speaking. Genuine dental crowns, especially high-quality ones, have a high level of biocompatibility with gum tissue, minimising the risk of inflammation or irritation.
Poor customer service and lack of long-term warranty
Establishments offering low-quality porcelain crowns often neglect after-sales service, which can leave customers struggling with issues post-treatment. They may not offer warranties, or they may provide only short-term ones, leaving customers unsure about the quality and longevity of the product. Therefore, it's important to focus not only on pre-treatment support but also on the warranty policy after getting cosmetic dental work.
Serious Harm of Using Low-Quality Dental Crowns
Many people mistakenly believe that dental crowns are simply an outer covering and that any type will suffice. However, you will want to reconsider once you learn the severe consequences of using low-quality crowns:
- Gum and Periodontal Inflammation: Low-quality crowns often have poor biocompatibility, leading to gum inflammation and damage to the soft tissues around the teeth, which can result in periodontal disease. This can affect long-term oral health.
- Wear on Natural Teeth: Low-quality crowns may have uneven hardness or be excessively hard, leading to strong friction against natural teeth, causing wear or even breaking them.
- Poor aesthetics: Low-quality crowns often have unnatural colours, unlike natural teeth, causing aesthetic issues. Additionally, uneven surfaces can lead to discoloration or cracks.
- Pain During Use: Low-quality crowns have poor durability and are prone to breaking or chipping when chewing, especially on tough foods. This can cause pain, discomfort, and the need for replacement.
- Risk of infection: If the crown does not meet quality standards, it may not adhere securely, leaving gaps between the crown and gums and allowing bacteria to enter, leading to infections and oral diseases.
- Damage to Tooth Pulp: If low-quality crowns are poorly fitted, they can increase contact between the crown and the tooth pulp, causing damage to the pulp and leading to inflammation or infection.
