In this idiom based question, select the option that best explains the meaning of the expression "Teething problems" as used in everyday English.

Introduction / Context:
This idiom question focuses on the phrase "Teething problems". The expression comes from the literal idea of a baby experiencing discomfort when its first teeth start to emerge, but in business, technology, and everyday conversation it is used metaphorically. You must choose the explanation that captures this figurative meaning correctly.

Given Data / Assumptions:

• Idiom: "Teething problems".
• Options:
  • Oral problems.
  • Problems at the start of a new project.
  • Problems for quite a long time in adjusting in the new place.
  • Problem of having good dentist.
• We assume the question is testing your knowledge of the metaphorical sense commonly used in organisational or technical contexts.

Concept / Approach:
Literally, teething problems refer to the difficulties babies face when their first teeth come out. Metaphorically, "teething problems" describes minor difficulties, bugs, or issues that occur during the early phase of any new system, project, or arrangement. These are not long term crises, but initial glitches that are expected and usually temporary. Therefore, the correct explanation mentions problems at the beginning of a new initiative, not general health problems or long term adjustment issues.

Step-by-Step Solution:
Step 1: Recall typical usage. Managers often say, "The software has some teething problems, but they will be fixed soon." This clearly refers to early stage issues. Step 2: Look at option B: "Problems at the start of a new project." This matches the idea of initial difficulties in new undertakings. Step 3: Examine option A: "Oral problems." This reflects the literal sense related to teeth, but the idiom in exam context usually expects the figurative meaning. Step 4: Examine option C: "Problems for quite a long time in adjusting in the new place." This suggests prolonged, continuing difficulties, whereas teething problems are normally short term initial issues. Step 5: Examine option D: "Problem of having good dentist." This is too specific and literal, and does not match normal idiomatic usage.

Verification / Alternative check:
Consider examples from news articles or project reports. A headline might read, "New metro line faces teething problems in first week" or "The startup has overcome initial teething problems." In both cases, the phrase clearly refers to early difficulties shortly after launch, which matches option B exactly. None of the other options would fit naturally in these sentences. You would not write "faces oral problems" or "faces problems of having good dentist" about a metro line or startup.

Why Other Options Are Wrong:
Option A restricts the meaning to literal dental issues, which is not how the idiom is used in business or general discussions.

Option C implies long lasting difficulties in adapting to a new place, not temporary early stage issues.

Option D focuses on finding a dentist, which is far removed from the figurative sense in which the idiom is typically used.

Common Pitfalls:
Some learners are tempted by the literal picture suggested by an idiom, especially when they see words like "teething" that obviously relate to teeth. However, idioms often shift far away from their literal origins. For exam purposes, always think of how you have seen the phrase used in reports, articles, or conversations, not just what the individual words suggest. Remember that "teething problems" has become a standard phrase meaning early difficulties with a new system or arrangement.

Final Answer:
The idiom "Teething problems" means "Problems at the start of a new project".
