How does a J220 tooth root infection develop?
Jul 16, 2025
Hey there! I'm a supplier of J220 teeth, and I've seen a lot of questions about how a J220 tooth root infection develops. So, I thought I'd share some insights based on my experience and the knowledge I've gathered over the years.


First off, let's talk about what a J220 tooth is. It's a type of tooth used in heavy - duty machinery, especially in excavators and loaders. These teeth are designed to withstand a lot of stress and wear, but like any part, they can develop problems, including root infections.
1. Initial Wear and Tear
When a J220 tooth is first put into use, it starts to experience wear and tear. The tooth is constantly in contact with hard materials like rocks, soil, and gravel. This continuous friction can cause small cracks and chips on the surface of the tooth. At first, these might seem insignificant, but they can be the starting point for a root infection.
As the tooth works, dirt, debris, and moisture can get into these tiny cracks. The debris can carry bacteria, which are just waiting for a suitable environment to grow. And those cracks provide the perfect place for them to start setting up shop.
2. Bacterial Invasion
Once the bacteria get into the cracks, they start to multiply. They feed on the organic matter in the debris and the metal of the tooth itself. The metal in the J220 tooth contains elements that can be broken down by certain types of bacteria.
As the bacteria grow, they produce acids as a by - product of their metabolism. These acids start to corrode the metal around the cracks, making them deeper and wider. This is the beginning of the root infection. The bacteria are slowly working their way towards the root of the tooth, where the situation can get even more serious.
3. Spread to the Root
As the corrosion progresses, the bacteria eventually reach the root of the J220 tooth. The root is a critical part of the tooth because it's responsible for holding the tooth firmly in place on the adapter. When the bacteria reach the root, they can cause significant damage.
The root is usually made of a different material than the rest of the tooth, often a more malleable metal to allow for a better fit. This different material composition can make it more vulnerable to the corrosive effects of the bacterial acids.
Once the root is infected, the tooth starts to lose its structural integrity. It becomes weaker and more likely to break or come loose from the adapter. This can be extremely dangerous in a heavy - duty work environment, as a loose or broken tooth can cause damage to the machinery and pose a risk to the operators.
4. Impact on Performance
As the root infection worsens, the performance of the J220 tooth is severely affected. The tooth becomes less effective at breaking through hard materials. It might not penetrate as deeply or as easily as it used to. This means that the machinery has to work harder to achieve the same results, which can lead to increased fuel consumption and wear on other parts of the machine.
Also, the weakened tooth can cause vibrations and uneven stress on the adapter and other components of the machinery. Over time, this can lead to premature wear and failure of these parts as well.
5. Preventive Measures
To prevent a J220 tooth root infection, regular inspection is key. Operators should check the teeth for any signs of cracks, chips, or corrosion on a daily basis. If they notice any small problems, they should address them immediately.
One way to prevent bacteria from getting into the cracks is to keep the teeth clean. After each use, the teeth should be washed to remove dirt and debris. Applying a protective coating can also help. There are special coatings available that can resist corrosion and prevent bacteria from adhering to the tooth's surface.
