What causes the flesh underneath the teeth to turn red and purple?

The reddish purple color of the flesh underneath the teeth can be caused by congenital development, metal crowns, inflammation, vascular disease and other factors.
1. Congenital development: congenital development leads to more melanin cells in the gums, which may lead to the reddish purple color of the flesh under the teeth.
2. Metal crowns: metal crowns are made of cobalt chromium alloy and nickel chromium alloy, etc. When these metals exist in the mouth for a long period of time, the metal ions may penetrate into the gums, resulting in reddish-purple color changes of the flesh underneath the teeth.
3. Inflammation: Inflammatory diseases such as periodontitis or gingivitis can lead to long-term stimulation of the gingival surgery, which can lead to the reddish-purple color of the flesh underneath the teeth.
4. Vascular disease: congenital vascular disease or vascular malformations and other vascular diseases in the gums, the gums can appear reddish-purple tortuous veins, which can appear color changes.
When the flesh underneath the teeth is reddish-purple, you should consult a doctor in time, and under the guidance of a specialist, you should actively carry out appropriate treatment, which will help to alleviate the uncomfortable symptoms as soon as possible.
